Without looking at the patches involved, I'd have to assume that the 
2.2.13ac3 patch changes things that the 2.2.13-14 patch also changes, 
possibly in incompatible ways. You'll most likely have to apply the ac3 
patch manually, -after- you have applied the 13-14 patch, and hope the 
changes to .14 don't break ac3. If they do, you're stuck with .13.

Sometimes it'll detect a reverse patch when you apply two patches that 
both include the same addition. Like this:

.13:
	funcA();
ac3.patch:
	-funcA();
	+funcB();
.14.patch:
	-funcA();
	+funcB();

So it figures that you really meant to switch back to funcA, since a 
reversed patch is when the original and modified file arguments are 
swapped. If this is the case, you should be okay, and hopefully it just 
means that parts of the ac3 changes got put into .14.
