It would depend on the district rules (if any). Most districts that have rules have a cap on point differentials ... we have a 21 point cap in our district (that means a 70-0 win only gives you a 21 point win for tiebreaker purposes).
In fact, last year in D2-4, we had a three-way tie for first place: Heritage, Lifegate and Town East.
Lifegate beat Town East 60-21; got 21 points for the tiebreaker
Heritage beat Lifegate 30-16; got 14 points for the tiebreaker
Town East beat Heritage 38-34 (I think) and got 4 points for the tiebreaker.
So, Heritage is +10, Lifegate +7, and Town East -17 and that determined playoff position.
