i think you're not using the correct leaderboard. if you want 'scores' to add up, you need to use the most wins leaderboard 

o my god cries

That will show the scores people made and it will not add up because it's considering particular games not particular users. Like Jung said, you'll need a Most wins leaderboard, either daily, weekly, monthly or forever and ever (lol).
