Two quick points. Whether an off-the-shelf approach is available depends on the shelf. The literature on analysis of ranking data may have one. I'm sorry that I don't know, but I have not needed to analyze such data. The score is only ordinal outcome, not a real quantification. Beyond that, the ranking imposes a constraint. People are often willing to treat scores as measurements, but one can't finesse the ranking.
