Tag->Filename allowing for duplicates

I would like a script that converts the tag information to the directory structure and filename, but I need it to allow for duplicates. At this time I still want to keep them as I have to go through and manually verify which is the better copy. Has someone written a script that will handle this?

Maybe add a "(copy)" at the end, or some other repeating character (should there be more than 2 copies). Any help on this would be appreciated

edit: BTW, I have had a search of these forums, and could not find anything that seemed to do what I was after... I went through the functions, I was hoping to find something like $ifexists(filename,new_filename) but alas, it was not to be found
