Seriously I hope someone figures out how to fix these things and add some weight to them. I wish they behaved like the regular skeletons and broke apart. Really hurts the immersion. Whoever figures this out will be my hero.

Huh. I have not had any really noticeable bouncy dragon skeletons or wandering ones since the 1.3 patch. Running 1.4 now and have killed several. They don't do anything weird.

I'll agree they are better but they still contort and flop around when they die. That and the fact that they are still completely connected. For kicks kill one on an incline.

You can still hit them with a low-level "Raise Zombie" spell and make them go flying all over. Either the 1.3 or 1.4 patch clears away the skeletons pretty quickly, though.
