Has an AFL game ever ended 110-31?
Exactly once. On July 13, 1974, Hawthorn beat Sydney 110-31, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 110-31 in league history.
That makes 110-31 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 111-31 has happened 1 times and 110-32 has happened never.
