I hate to sound like a nag, but this question has been bought up so many times. Even just a general search would show countless threads, the problems is that iTunes doesn't use actual tag standards. And yes the problem is on iTunes end. And no the Foobar devs are not planning on fixing that isn't broken (from Foobar's end), they do not plan on writing up some hack to make it work in iTunes. And lastly yes Foobar .9* uses ID3v2.4 tags.
Solution 1: Try using an external program like MP3TAG to convert ID3v2.4 tags to ID3v2.3.
Solution 2: Don't use iTunes -> But what about my iPod?
