I recall people experimenting on this. From what I've heard, it is random every time. Although the side that pushes first will always win if nobody interferes. For this reason, I find Howling Abyss better for 1v1. I don't think Riot intended one side to win minion pushing alone, but it's annoying to lose a game just because of randomness.

The way it works is that some minions are initially positioned better to attack sooner and thus gradually win the push increasing the waves size. It eventually bounces back and forth, but due to the first wave of minions dealing more damage to the turret initially, that side eventually destroys the turret and wins eventually. Normally people emulate this killing only creating a one minion difference between the waves and leaving to allow a monster wave to build up, but in this case it is completely random.
