The convention for reporting sports scores is to always have the score of the winning team first and then designate a winning (or losing) team. For example here are a handful of scores from BYU's season:
BYU-SMU: BYU won 18-15, or SMU lost 18-15
BYU-OSU: BYU won 38-35, or OSU lost 38-35
BYU-Utah: BYU won 22-21 or Utah lost 22-21
