I have to admit- I don't reckon that is true, although I wish it was. All the mice I have ever brought are bloody-nosed indicating they have been bashed, quite hard in some cases.
Actually, the bloody noses can happen for several reasons:
Bashing them (as you've said)
Overdose of CO2 while alive (you are NOT aiming for 100% concentration)
Freezing/Thawing damage to blood vessels in the nose can also cause bleeding from nose and mouth - no matter how the rodent was frozen. I would, in frozen rodents, assume this means the rodent's thawed out at least once and been refrozen.

Ask at the counter as our local Halfords keeps them in a fireproof store cupboard in the back. So they are not always on view. (because they would explode in a fire not because they are flammable!)
