Scoring applications is hard! Sometimes when you score, you have a certain percentage of applicants at the top, but then some in the middle who are tied and you can't select the number you need. Our suggestions are:
Recruit some more volunteers (maybe former coaches or organizers in other cities) to help you score. More votes lessens the likelihood that you'll have ties.
Rescore those applications with your team, to see if a second look at the applicant helps you form a consensus.
Accept the applicants who applied first, if there is a tie, and put the rest on a waiting list.
