I had my score reviewed for a score I sent while SSing. I haven't got a reply yet but other scores that were reviewed after have come back fine. It was on a brand new shell I made that day. I'm thinking they must have let me off or something...
Don't really know.
TNT can take up to a week to review scores and are usually more careful with newer accounts, although since your other scores were accepted, TNT most likely just ignored your score completely x)~
(Sometimes TNT just plain ignores a review)
You could try sending in another score though? o: /Idunno I usually don't bother doing any game related things on neopets cx
