To debug your (messy) code, put the print statements throughout the script. You'd see immediately, that variable "pos" is always empty.
You try to set the 'pos' var here:
Code:
  if	($4 == "(511, 69)"){pos=0;}

But the fourth field is not this, it is an integer before:
Code:
 Trial: 7 706907 2 (197, 383) 1 514.30 387.90 7 1149 0 0 2 1 mailbox_c.jpg mailbox_c.jpg

Furthermore, the pair (197, 383) has a space inbetween, so it's actually two fields. But wait, the FS is set to tab character, so you actually have only one filed ($1) in each line, since there are no tabs there. You could take out the FS="\t" line, and test for $5 $6:
Code:
  if	($5 $6 == "(511, 69)"){pos=0;}

but honestly, that code has so many errors, i suggest you rewrite it. Try to use 'case' statements, they are much more easier to read and less prone than nested if statements.
And I would take out the space from the paired values (511, 69) change to (511,69) so that the input is properly delimited, at least.
Good luck.

git-sh-setup

GIT-SH-SETUP(1) 						    Git Manual							   GIT-SH-SETUP(1)

NAME

       git-sh-setup - Common git shell script setup code

SYNOPSIS

       . "$(git --exec-path)/git-sh-setup"

DESCRIPTION

       This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish
       scripts and/or are writing new ones.

       The git sh-setup scriptlet is designed to be sourced (using .) by other shell scripts to set up some variables pointing at the normal git
       directories and a few helper shell functions.

       Before sourcing it, your script should set up a few variables; USAGE (and LONG_USAGE, if any) is used to define message given by usage()
       shell function. SUBDIRECTORY_OK can be set if the script can run from a subdirectory of the working tree (some commands do not).

       The scriptlet sets GIT_DIR and GIT_OBJECT_DIRECTORY shell variables, but does not export them to the environment.

FUNCTIONS

       die
	   exit after emitting the supplied error message to the standard error stream.

       usage
	   die with the usage message.

       set_reflog_action
	   set the message that will be recorded to describe the end-user action in the reflog, when the script updates a ref.

       git_editor
	   runs an editor of user's choice (GIT_EDITOR, core.editor, VISUAL or EDITOR) on a given file, but error out if no editor is specified
	   and the terminal is dumb.

       is_bare_repository
	   outputs true or false to the standard output stream to indicate if the repository is a bare repository (i.e. without an associated
	   working tree).

       cd_to_toplevel
	   runs chdir to the toplevel of the working tree.

       require_work_tree
	   checks if the current directory is within the working tree of the repository, and otherwise dies.

       require_work_tree_exists
	   checks if the working tree associated with the repository exists, and otherwise dies. Often done before calling cd_to_toplevel, which
	   is impossible to do if there is no working tree.

       require_clean_work_tree <action> [<hint>]
	   checks that the working tree and index associated with the repository have no uncommitted changes to tracked files. Otherwise it emits
	   an error message of the form Cannot <action>: <reason>. <hint>, and dies. Example:

	       require_clean_work_tree rebase "Please commit or stash them."

       get_author_ident_from_commit
	   outputs code for use with eval to set the GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL and GIT_AUTHOR_DATE variables for a given commit.
