Dreamlo Speedrunning leaderboard

I'm making a puzzle game that has a leaderboard at the end, which displays the top ten fastest people to complete the game, but the leaderboard sorts the entries so the person who took the longest gets the best score and the person with the shortest time goes at the bottom of the leaderboard

How do I sort the leaderboard so the person with the smallest score appears at the top of the leaderboard?
