iTunesConnect has had an overhaul in recent years to give it a much shinier and more reliable frontend. I believe the original was closer to the original WebObjects code, and now they've extracted out the user-facing bit into something a bit more modern. There's a lot of legacy WebObjects stuff around the iTunes backend, and my guess is that it's good engineers held back by old tech, rather than just bad engineers.
