Applescript to update MP3 Spotlight tag from iTunes tag

Here is my situation. I have a large iTunes library that has songs tagged with the "Year" in iTunes. I have a Hazel Rule for the noodlesoft hazel software which reads from Finder's "Year Recorded" metatag. I would like an applescript that can recursively for all tracks selected read the iTunes "Year" track and embed it into the file's "Year Recorded" metadata so Finder/Spotlight will then see that information. I saw this: Applescript to update year tag for audio files but it is not what I need. Any help on this would be highly appreciated!
