Fix several missing properties on `MultiplayerScore`

You wouldn't think this would be an actual thing that can happen to us,
but it is. The most important one by far is `MaximumStatistics`; that
is the root cause behind why stuff like spinner ticks or slider tails
wasn't showing.

On a better day we should probably do cleanup to unify these models
better, but today is not that day.
