  Order statistics provide an intuition for combining multiple lists of scores
over a common index set. This intuition is particularly valuable when the lists
to be combined cannot be directly compared in a sensible way. We describe here
the advantages of a new method for using joint CDFs of such order statistics to
combine score lists. We also present, with proof, a new algorithm for computing
such joint CDF values, with runtime linear in the size of the combined list.
