Okay so, I have my scoreboardstats config set up so it should display Ping, then Online players, then faction power, Exactly like this, config below.

Scoreboard:
Title: '&c&lStats'

seconds

For instant updates you can or 1 and it will update every second

Update-delay: 1
Items:
# The Title must have under 48 characters
# Title: Type
'&f&lPing »': '%ping%'
'&f&lOnline »': '%online%'
'F Power': '%power%'

but in-game it gets sorted as "Ping, F power, Online"? Can anyone help me?

It's minecraft behavior, because it's used to be a leaderboard. Therefore the highest number is a the top.
