Well, like I said - the script I whipped up depends on a fixed number of
fields (words separated by "_") being present in the filename. If any of
them are different, then it's going to give you the weird behavior that
you're seeing here.
I'd suggest going with Mark's sed solution - since it's not counting
fields before getting to the part that you want to get rid of, I suspect
it will work better for you. :-)
