I haven't yet had a chance to read the paper, so excuse me if this is missing the point, but it seems to me that this is just a product of the thermodyamic arrow of time. If the laws of physics mandate that the time-reversed process is impossible (as appears to happen in a few cases) then the "Price principle" doesn't apply. But if the process is allowed by the LOP but highly unlikely, that's most likely down (ultimately) to the low-entropy conditions near the Big Bang.
