Sorry, I didn't make it very clear.
I'm developing some games myself + sometimes I need to delete a top score after somebody found a way to cheat. When I do this the "Best Score Ever" still remains.
If you go into "Arcade" in the admin panel then "Score Tools" the second from last option is:
"Update the Best Results"
This should transfer the current high scorer to the best score ever, but it doesn't work!
If I could fix this it would save me a lot of messing around in PhpMyAdmin
