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.
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.
