As a crusty and sexist old dinosaur let me say straightaway that, in line with the OP's cri de coeur for a return to traditional values, I would most certainly base my marking in such a competition on markedly crude and lecherous assessments of the gels' looks. As for getting them to change a tyre, I believe the tried and trusted method is to stand by the roadside, looking helpless and forlorn, and flashing a shapey leg at likely looking chaps in motor cars as they pootle by. I have to admit though that this has never worked for me....
