Model to store biggest score

[Richard Grossman]

Hi,

I trying to find a model where I can keep the list of biggest score for
users.
it's seems simple but I'm stuck here .
For example user1 score = 10
                    user2 score = 20
                    user3 score = 30

Query: Top score (2) = user3, user2
If someone have made something similar thanks for sharing
