I have no idea what you think is going on with the track # being included in the tags, but I think you're inferring the wrong things.
Or you could load both sets of files into your players, sort them by title or artist, and then line things up so you can copy your old rating into the new file. Or just relisten to everything (my biased recommendation).

Good luck there, rebel.
