We don't know the human characters' relative ages and can only make broad assumptions based on their pony counterparts. FWIW, the fact that Snails was permitted to play in an adult team in Buckball Season suggests that he and Snips might be somewhat older than the CMCs. Because Ponyville is a small community, it may not be possible to split the school into grades. Besides if anypony screams 'left back' it's Snips and Snails!

So, it's possible that the human!CMCs were in a different grade to the Mane 7 and didn't get to go on the trip.
