I’d put them oldest further from the hinge. My logic is that they’d be closer to me when I open the door that way (same logic applies whether you store them in the door or fridge). However, of you have a weirdly designed fridge like mine, it makes more sense to keep them on the right side of the body of the fridge because we have double French style doors and it can be sort of cumbersome to try and open the right door and grab the milk if it’s sitting toward the middle away from the hinge due to the left door not being open and my arm bumping it / it being partially in the way. The left side is ruled out completely because there are shelves that are too low and don’t allow enough headroom for the milk.
