I typically only recommend freezing for seeds that are completely dry. I wonder if acorns are one of those seeds that shouldn't dry out? If they should be planted immediately? Or be stored refrigerated?
Acorns are indeed what we call a recalcitrant seed and those are plenty ripe enough. You must store them moist. In temperate climes moist and cool, that is refrigerated. Not too moist. Think wrung out rag or paper towel moist. In a sealed zip lock. 10% bleach solution for a few minutes can help with surface pathogens. Then rinse throughly. Check them frequently in storage and as long as radicles haven't emerged you can bleach again with 10% bleach.
Immediately plant or discard any imperfect ones. Particularly with holes. They may still grow into trees, but won't store in the fridge and fungi can spread to the good ones.
Do not freeze them or dry them. That will kill them. Ship them, if necessary, quickly. Best to plant them asap.
