This proves nothing at all. Although I'm sure those numbers have the meaning, we shouldn't add speculation.

Now, If I were to speculate, I think those might be the episodes with at least one song in them. We already know, that #9 has a song, and #5 will air in 1.5 weeks, so it won't take long until it becomes either busted, or plausible.
