1. Some of the holes are on the top of the horizontal stabilizer, some are on the burnt side of the plane and other on the unburnt side.
2. Looking at the latest video from what is said to be a CCTV camera, one can seen a large quantity of debris from the ground being flung by the velocity just before ground impact.
3. Photographs of the ground itself show a lot of gravel stone around the crash site.
4. The direction of the rudder damage.
All of these factors seem to point to some of the holes being a result of the impact with the ground itself.
The area around the hole in the tail fin (which is metal; only the control surface on the NG is CFRP) shows no damage or indentation from rocks on the ground. I find it hard to believe a rock sitting on the ground could put a clean hole into the tail fin. The plane is traveling at a fraction of the speed at impact (400mph) vs that of fragments from an explosion (2000mph).
I agree that the area immediately around that hole does not show damage that may have been caused by the object that punched it. However, there is a scratch towards the top of the fin on the metal surface which proceeds into a tear of the control surface. There is also significant damage at the base of the fin. The one consistency about all of these marks on the tail fin (including the hole) is that they seem to have been propagated from the unburnt side (or the starboard side) of the surface. For me, this is evidence that the damage occurred after whatever it is that caused the fire, not before.
