Developing a Percentile Ranking

Situation: Businesses are assigned a rank of 1 to 5. Based on rank, each is subject to an investigation 2 to 4 times a year. Investigation yields a numerical score from 0 (no violations) to infinity. For each rank, using scores for that rank over time, develop ranges of scores which represent 25th, 50th and 75th percentile. The 25th percentile representing the best businesses and lowest scores.

The 50th percentile is the median, so lots do that first. Are you looking for the median score for each rank or for some kind of global median ?
