You see, Skeleton and Zombie are templates applied to any corporeal creatures with skeletal systems. If I remember correctly, a corpse is defined as an object (Can someone back me up on/disprove this? SRD does not hold anything for me), not a creature. Thus corpses are ineligble for becoming skeletons and zombies.
