Some paper search results include columns with score graphs. Click on a score column heading to sort the paper list using that score. Search > Display options changes how scores are sorted. There are five choices:

Counts (default)
Sort by the number of highest scores, then the number of second-highest scores, then the number of third-highest scores, and so on. To sort a paper with fewer reviews than others, HotCRP adds phantom reviews with scores just below the paper’s lowest real score. Also known as Minshall score.
Sort by the average (mean) score.
Sort by the median score.
Sort by the variance in scores.
Max − min
Sort by the difference between the largest and smallest scores (a good measure of differences of opinion).
My score
Sort by your score. In the score graphs, your score is highlighted with a darker colored square.
