First I will preface my statement with this one:
I am not totally familiar with the exact situation.
Trials is about the ability to control a motorcycle, not how long you have existed on this planet.
So any tie breaker should be based on ability to control the motorcycle. I.E. section ride off, Wheelie contest, bunny hops, balance contest, being able to urinate into a gas can 5 feet away while doing a nose wheelie. etc. etc.
