::: Ranked Robin uses ordinal ballots, so it can't be Score. The first degree tiebreaker states: "Declare the tied candidates finalists. For each finalist, subtract the number of votes preferring each other finalist from the number of votes preferring them over each other finalist. The finalist with the greatest total difference is elected." That is, for each finalist X, X's score is sum over other finalists Y: (number of voters preferring X to Y) - (number of voters preferring Y to X).
::: Suppose that a candidate is ranked first on a complete (untruncated) ballot, among the finalists. Then it gets one point from that ballot for each other finalist. If the candidate is ranked kth, it would get one point for each finalist, minus (k-1) points for the ones ranked ahead. So its score from a ballot is linearly related to its position, which describes (I think) the weighted positional system of Borda.
