I can't see this with your last posts, the order is correct/as usual to me.
Also, sometimes it happens your answer is the first of a new page of the topic, putting it, seemingly as "first"/"top" answer.
It would be nice if you could provide more details (like the topics in which this happened for example).
Maybe Tom was messing with the forum at the very time you posted and things went back to normal since.
Finally last option possible is also drugs.
