Another user reported this problem and I realized I never posted the result: Mac OS X (later versions) don't like multiple copies of the same app on your hard drive(s). This especially kills AppleScript because it needs to target an app and it gets really confused when there are multiples. So the solution is to look around your hard drive for other copies of Airfoil and delete them.
