Not sure why Google's doing that (outside of the overstated fact that once they find a URL they won't stop looking for it, ever). One trend I've seen in official (government) websites is moving to CMSs using the /index.php/ handler for SEF pagenames. I have a CMS like this also but it removes /index.php/ if you want but in your case it's up to Google whether or not they remove those references, 410 might not have the intended effect with them, as if they keep a permenant archive of URLs to compare old and new versions of sites so they don't miss a thing.
