Just a guess - pistons were selected from an inventory with a range of slight variations from standard size based on hand-fitting to the bore - #s you see might possibily be related to that. Can't say I've ever seen it done in that manner, though I've seen odd numbers stamped on piston heads which I assumed to similarly be an aid in hand-selection.
