However, the Condorcet winner criterion is quite easily and
unambiguously applied to Range Voting ballots, since a ranked ballot can
be easily derived from a Range Voting ballot.  

In fact, the Condorcet winner criterion has nothing to do with the
ballots, and everything to do with the electorate.  You only need to
answer the question "if head-to-head elections are conducted among all
of the candidates, is there a candidate that wins every election they
are part of?"  Given that its possible to derive the electorate's intent
from a set of Range Voting ballots, it's hard to argue that there's
ambiguity there.
