Sounds like this is something you should be reporting to Apple through the established beta feedback mechanism. It may be intentionally disabled, or it may be a bug. If it's not on the listed known issues (on the beta download page), it's worth reporting.
My audiobooks syncs but I have to pick them one by one in iTunes. When I choose sync all its screwed up. But I have 120 audiobooks, If I pick 119 of them manually no probs.
They show up in iBooks on my iDevice though but that's fine.
