You can't disguise your self as a dead body? How could Sense Motive possible reveal whether the they are undead or just mundane bodies. Sense Motive is a social skill which relies on body language, speech habits and mannerisms non of which are in play here. Spot should be the skill use to determine whether they are undead or not. That leave us with two chocies the cant either be using Hide or Disguise. Since they are in plain sight I don't think hide makes much sense. They are trying to portray themselves as something they are not, merely base on circumstance and appearance. That fits Disguise better IMO than any other skill.

Look at the mechanics of Perform do you see any provision for deceptive use? I don't. Skeletons can use Perform it is possible for them to dance and play some instruments. Bluff requires interaction which is not happening here.
