I was talking about scores as outputs, not inputs :-)

I.e. a Condorcet method that doesn't just say "Montroll is in first, 
Kiss is in second", but whether Montroll's win was comfortable or close 
(and similarly, if Wright was close to passing Kiss, Simpson close to 
Wright, etc.)

The voters would still use plain old ranked ballots.

The method would just return more detailed information -- like how FPTP 
shows the strength of victory on a scale (as percent of first 
preferences gained), even though FPTP isn't a cardinal method.

As for STAR strategy, it makes sense that STAR would behave that way if 
everybody does 5-1-0, because that's more or less reproducing the logic 
of IRV/TTR (first preferences count a lot, other preferences don't). I 
suspect that STAR strategy is less unbalanced, though; that some times, 
5-4-0 is good, other times 5-1-0 is good, and you don't get skewered the 
same way you can in Approval if you get it wrong.
