Hmmm, does an ordered dictionary actually solve this problem? It seems like you want to retrieve based on player id, but get the top N based on score. An ordered dictionary would be ideal if you wanted to retrieve and get the top N based on the same key. I guess you could use two data structures, with one of them being an ordered dictionary. But then the ordered dictionary doesn't actually have to support lookup; you could just use a heap.
