Shane,
. . .
My key concern was:
It doesn't look like it changes any files or folders, but I can't be for sure, so I don't want to run it to see what happens.
So, it looks like to me that the purpose of your script is to show a better method of selecting the next Finder Item after the current selection,
without actually moving the selection.
Correct, or not?
