I can only really reiterate this.
What's being suggested about a clan's history being used as a tiebreaker is just blatantly open to abuse. It'd also definitely cause a lowering in the perceived 'fairness' of the outcome of a war.
Besides, if you want to get into the 100s of streaks, you do serious, controlled roster manicuring instead of showing up with maxed or near maxed 13s. If you do the latter you'll eventually run into the perfect ties before 100-200 streaks.
