I did submit the score, as you can see from the picture i attached to my original post.
My score was registered by the game and still shows up as "my best score" but not as the high score.

Weird glitch I guess.

I've tried the golf game, it's really good. Except Ben seems to have got an incredibly high score, which is annoying! Ah well, I'll beat him one day, if not in the game then with a big stick.
