Stacking in this case doesn't mean that you can make a stack of them, it means that the EFFECTS stack with each other. If the effects didn't stack, no matter how many skulls you had equipped you'd only get +2 defense. (However, I'm not even sure if they [the effects] DO stack, I'm going to have to experiment a bit.)
