VS 2008 Score Board, Having A Sorted List Sort On Integer?

I keep track of a score system for all users in a sorted list;

dim Scores as new sortedlist(of string, integer)

I can easely increse points for a cirtain person by;

scores("peter").value += 1

Now I need to display a top x list of the users, if users have the same score, it should sort alphabetically on the name. Of course it's also possible that users have the same score.I've already tried to make a new sorted list with as key the score, and added to that score the username. Later when displaying the scores, I've replaced the username with nothing. The only problem in this solution is that the numbers are sorted on asci value which has this order:

0
1
10
2
3
4

Also, if you make a sorted list like this:

dim Scores as new sortedlist(of integer, string)

You can't have two people with the same score... So, there must be something possible with the iComparer to sort on integers right?
