I believe the latest version of Tag&Rename can do this. I have not tried it (but will soon), but I believe it can copy a directory's worth of tags to the files in another directory if they both have the same number of files. ie: two directories, one has a 192 rip of a CD and the other has a 320 rip; copy tags from 192 directory to 320 directory.

Tag&Rename rocks even if it can't do ID3 duplication, so check it out. And if it does dup tags, please post back!
