By %files_last_mod%, do you mean the files last modified timestamp? Or are you wanting to see the song's last modified timestamp? Having this included on a print-out is not a simple thing, and I'm not even sure where it would make sense to configure that, especially if it was possible to include other variables. It seems to me like it would pretty simple to just add an annotation on the first page of the file that indicates what version of the file you are using. You would just increment that annotation if the file has changed. This would basically serve the same purpose.
