) The only way I can see around this "some hosts are more equal than others"
) scenario is to have an additional sort key that is set to a random number,
) but I'm not sure it's worth the trouble.  Any other ideas/comments?

The easiest thing to do would be to multply all MX preference values by
some number N, say 256, and add a random number in [0, N-1] to each.
Just make sure you can't overflow and everything will be groovy.
