Online Highscore

Hi, in my game I want to display the top 100 scores of all the players that play my game. I guess I’ll need to make some sort of username textbox for the player to save their usernames in and if their high scores are good enough for top 100 then I want their user name to display on the leaderboard with their score next to it. I also want the scores to be in order from best which will be 1 to 100 which is the least.
Thanks
