Kickball leagues are mostly social, and the standings keep up with that: win-loss-tie record, with ties allowed when the game hits its time limit. Some leagues turn the record into points (2 for a win, 1 for a tie), and some rank on winning percentage with a tie as half a win. Both give the same order.
Runs for and against (RF, RA) and run differential are the natural tiebreakers. Scores are low enough that a single big inning can swing run differential, so many leagues cap runs per inning.
