Currently, leaderboards for challenges are displayed in ascending total distance order. Instead, it should be ordered first by score (descending), then by time (ascending), then by distance (ascending).

When you click on a map and see the non-challenge overall leaderboard it already displays them this way.

With the current ordering system, a 1 hr 25k with a total distance of 20m appears first on the leaderboard over a 5 minute 25k with a total distance of 30m, but within the community the latter would be considered a superior game.

I attached two images, the first is the overall leaderboard for A Moving World which shows the ordering the "right" way. The second is the results for the daily challenges which shows the ordering the "wrong" way, as the 7 minute game should be in first place.
