In my experience, when Kevin rattles off a list of failed criteria, it's
only a matter of time before he comes up with an example that shows you
why at least one of them is really, really important.
If all you're looking for is something better than IRV that can be
boiled down to a single score, you're better off going with Approval or
Range. My sense is that by insisting on shoehorning a Condorcet winner
method into a single score, you're treating the Condorcet winner
criterion as an absolute priority, while ignoring all of the others.
There are good reasons to believe that the other criteria are at least
as important as the Condorcet winner criterion.
