I agree that there are possible utility distributions that favor a  
vote for B.

I don't agree that {100, 10, -200} is a reasonable interpretation of A  
 >> B > C, which, if it means anything, means that the utility gap  
between A & B is larger than that between B & C.

Aside from that, I think we're more or less on the same page here.
