Why that complicated? Try
Code:
awk '
FNR == 1        {FC++
                 FN = FILENAME
                 sub (/.txt/, "-new&", FN)
                }
FC == 1         {VAL[$1]
                 next
                }
FC == 2         {CSV[$2] = $3
                 next
                }
$1 in VAL       {$1 = CSV[$1]
                }
                {print >  FN
                }

' FS=, val.txt file/location/csv FS=" " data-*.txt

It will read the val and csv files and put their values into respective arrays, and then pick any data*.text file around and convert it into a "new" one. If you want to restrict the file selection to 1 .. 31 but skip non-exististing ones, try using shell patterns. You may need to adapt the field separator FS.

NAME

       sagasu - GNOME tool to find strings in multiple files

SYNOPSIS

       sagasu [string [dir]]

DESCRIPTION

       sagasu  is  a  GNOME  tool to find strings in a set of files.  The user specifies the search directory and the set of files to be searched.
       Double-clicking on a search result launches a user command that can for example load the file in an editor at the  appropriate  line.   The
       search can recurse into subdirectories and can optionally ignore CVS directories.

       Two  optional  command-line arguments can be given: the first is the initial search string and the second is the directory whose files will
       be searched.  If only one argument is given, it is taken as the search string.  No search is actually started, but the  appropriate  fields
       are initialized.  Any subsequent arguments are ignored.

       More documentation is available through the application's Help menu.

BUGS

       The files to be searches are still assumed to be in Latin-1, not in UTF-8.  The same goes for the command-line arguments and  the  terminal
       to which Sagasu is connected, if applicable.

HISTORY

       Sagasu is a Japanese word that means "to search."
