Some AppleScripts from this site use a routine that checks for the version of iTunes you are running. Some of the scripts that use these routines are broken under iTunes 10. So when running a script with iTunes 10.0 you may run into a dialog that erroneously reports something like "This script requires iTunes 6.0.2 or better". This is not a bug in iTunes, but a problem with the way the script does the version check. (Long story short: the version number once was a number, but more modern versions of apps use a string. Thus "10.0" is not necessarily greater than "9.2.1" and the routine fails to accommodate this.) You can edit/comment out the version check routine yourself or wait until I get around to fixing the handful or so scripts that are affected. In that case, let me know if you see the error.
