I suggested that the OP discard let ( I've noticed that sometimes people use this thinking it is a regular assignment, perhaps because of previous experience with BASIC ). I pointed out that it is used for arithmetic purposes.
If the OP is aware of this and wants to use it then that is fine of course, but it can't hurt to note that in that case the script will only run in some shells, whereas $(( .. )) is portable. I agree with cfajohnson, that there is no advantage in using let (and there is a disadvantage).

ps2frag
ps2frag(1) General Commands Manual ps2frag(1)
NAME
ps2frag - obsolete shell script for the PSfrag system.
IMPORTANT NOTICE
The new PSfrag system no longer requires the ps2frag script; instead, it handles the processing entirely within TeX/LaTeX and DVIPS. I'm
sure you will agree that never needing to run ps2frag again is a nice convenience!
However, there are two significant differences in the way this new version of PSfrag works. Please make yourself aware of them:
1) XDvi is no longer able to determine where your PSfrag replacements should go, so instead it lines them up in a vertical list to the left
of the figure. This allows you to confirm that they have been typeset properly, at least. However, to confirm that PSfrag positions your
replacements properly, you will have to view the PostScript version of your file with a viewer like GhostView, or print it out. This seems
to be the only disadvantage to the elimination of the pre-processing step.
2) If you embed ' ex' commands inside your figures, you now need to explicitly _tell_ PSfrag to process these commands. To do so, use
usepackage[scanall]{psfrag} instead of usepackage{psfrag} at the beginning of your LaTeX file.
If you only use ' ex' commands in a small number of figures, then a more efficient might be to turn on ' ex'-scanning only for those fig-
ures. To do that, add the command 'psfragscanon' immediately before each relevant includegraphics or epsfbox command.
NOTES
See the PSfrag documentation for further information.
