After trying it out I'm not so sure. The missing scoring token (ie. round) was ice, and there seems to be a bonus for most ice. Not sure if that is supposed to be limited by piece availability though...
Scoring has varied greatly in our games, due to Saboteurs and whatnot. In the final round, we often use the region token to stand in for three of the money tokens of that same type. Instead of giving out three 1s, we hand out the 1 marker from that region. The marker is worth three points (or 6 or 9, depending on the marker), and the 1 is worth three pieces of ice.
