I think you might have to go to your foods eaten page for it to update [edit] Nope. I swear I got it to register somehow in the past though, but maybe it was just a long cache
Has your score updated yet? Mine's up to date now (but I just fed my gourmand a couple more foods so his count should update at some point)
Have you cleared your cache? Your number on the high scores table matches Foxie's food eaten page from what I can see
