You want more of an assembly line, not command calls for one file:
Code:
 
export zct=$start_no
find $top-dir -type f -name '*[a-zA-Z].[am][vp][i3]' | sed '
  /avi$/!{
    /mp3$/!d
   }
 /avi$/{
    /MP3/!d
   }
  s/.*/mv "&" $(( zct += 1 )).mp3/
 ' >/tmp/mvall.sh

Review before executing! You might take all the files for one dir and do them at once in the background (parallel), just wrap lines for each dir in parens with amp: (...)& More than one process renaming in the same dir makes for file contention.

shtool-mkshadow

SHTOOL-MKSHADOW.TMP(1)					      GNU Portable Shell Tool					    SHTOOL-MKSHADOW.TMP(1)

NAME

       shtool-mkshadow - GNU shtool create shadow tree using symlinks

SYNOPSIS

       shtool mkshadow [-v|--verbose] [-t|--trace] [-a|--all] src-dir dst-dir

DESCRIPTION

       This command creates a shadow tree of src-dir under dst-dir by recreating the directory hierarchy of src-dir under dst-dir and by creating
       the files of src-dir by linking them into the corresponding directories under dst-dir via symbolic links. When src-dir can be reached via
       relative paths from dst-dir, relative symbolic links are used, too. This high-level functionality is originally designed for developers to
       create copies of source trees.

OPTIONS

       The following command line options are available.

       -v, --verbose
	   Display some processing information.

       -t, --trace
	   Enable the output of the essential shell commands which are executed.

       -a, --all
	   Really shadow all files and directories in src-dir. Default is to skip CVS related files and directories, backup files, object files,
	   etc.

EXAMPLE

	#   shell script
	shtool mkshadow -v -a . /tmp/shadow

HISTORY

       The GNU shtool mkshadow command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later
       revised and taken over into GNU shtool.

SEE ALSO

       shtool(1), ln(1).
