How do the hi scores work?

Hi everyone, 
I have went from rank 0 - 110 in the past month and I'm just wondering why isn't my name appearing on the hi scores . Can anyone give me insight how that system works. 
Thanks

You need a subscribtion for beeing in top list. If you have no subscribtion you can get a rating of 1000+ but you won't be in the top list

If your a sub it'll appear, if not it won't.

You have to be 200 + to make the top score anyway
