It wouldn't have to be both ranks and scores. It could just be scores. But you then order the scores numerically to infer the rank. And you use the rank to find the Condorcet Winner. If there is no CW, then you use the scores from the candidates in the Smith Set to identify the winner from that Smith Set.

(The point of the above was to respect the Condorcet Criterion, and 3-2-1 voting does not meet that criterion.)
