Plugin For a Battle-Tower Leaderboard

Hey,
I am building a battle tower with 30 floors on my Pixelmon server, and I was looking for a way to display the top 10 players who have reached the highest. Preferably, the leaderboard can be accessed either by clicking into a chest, NPC, or just a floating leaderboard display. Also, it has to be automatically updated whenever a player succeeds another player on the leaderboard (if he/she gets to a higher floor).
I’m trying to avoid using signs on a wall because of the work and time that I would have to put in.

I saw this, but there wasn’t much documentation on it: https://ore.spongepowered.org/yinyangshi/YYS-ScoreBoard

Wouldnt be difficult to make if you can not find one then put it into plugin requests
