It's probably a hack. There are people like this on my leaderboard (although I've seen more obvious hackers, such as this person who used Devil Cookie with Drop of Choco, and their two treasures being Drop of Choco's Choccy Chunk and Cheeseberry's Smelly Slice.

I actually found this website that allows you to hack coins by pairing any Cookie with Drop of Choco, by getting much more coins from runs. If they can hack coins, they can likely hack scores too.
