I attempted to make a scrolling scoreboard and had some success anyway. You must though scroll down to see the leaders until the board is filled up more.
There is one line that can be changed to adjust how far the panel comes in horizontally. It is "self.ScoreboardHorzStart". This number is that it equals is how far from right of the screen it goes.
Well it could use some improvement perhaps, but at least it works.
Thread for discussion is here.
