You could spell it out:

A defeat (A,X) is weaker than a defeat (D,Y) if A is not the default
option and D is the default option.

A defeat (D,X) is weaker than a defeat (D,Y) if D is the default
option, and V(D,X) is less than V(D,Y).

A defeat (A,X) is weaker than a defeat (B,Y) if neither A nor B
are the default option, and V(A,X) is equal to V(B,Y) and V(X,A)
is greater than V(Y,B).

A defeat (A,X) is weaker than a defeat (B,Y) if neither A nor B are the
default option, and V(A,X) is less than V(B,Y).

A defeat (A,X) is weaker than a defeat (B,Y) if neither A nor B
are the default option, and V(A,X) is equal to V(B,Y) and V(X,A)
is greater than V(Y,B).

The catch is you should be looking at the V(...) stuff only if either
both A and B are the default option, or if neither of them are. I hate
writing these things in programming languages too :(

Maybe you could say:

The strength of defeats are determined as follows:
(1) defeats by non-default options are always weaker than defeats
by the default option; otherwise
(2) a defeat (A,X) is weaker than a defeat (B,Y) is V(A,X) < V(B,Y);
otherwise
(3) a defeat (A,X) is weaker than a defeat (B,Y) when V(X,A) > V(Y,B);
otherwise
(4) the defeats are equal

or something similar, with the idea that each rule is checked in both
directions before moving on...

Actually, A defeats B by 3:2. You meant:

3 ABD
1 BDA
1 DAB

How interesting. So they're not as equivalent as I'd thought. Hrm.
