Here if Tom and Dick each vote A=B, we get to the same destination as for
votes of A>B and B>A. I see this scoring as reasonable.

Here if Tom votes A=B, he has as much power as if he became twins, voting
A>B and B>A, giving these two an edge over other candidates.

EXCEPT, IRV only looks at one of your choices at a time. Try 10 A>Z, 9
B>Z, 8 C>Z, and 7 D>Z - I see 34 agreeing that Z is acceptable, A being
second, for 10 see A as acceptable, and A winning in IRV.
