https://security.stackexchange.com/questions?page=10&sort=votes shows questions with a score ranging from 6 to -1, while page 9 suddenly goes from 46 to 27 votes and sharply down from there. Page 11 starts again at 46 votes.
I reproduced this using Chrome 36 and IE11. I've also tried it using a few proxies and the problem remains. I sort of remember a similar issue when I was archive binging on Stack Overflow over a year ago.
