code: public static final <T> Ordering<Scored<T>> ByScoreOnly() {
      return Ordering.natural().onResultOf(Scoreds.<T>scoresOnly());
    }
docs: Comparator which compares by scores only. Beware: using this comparator in things which depend
  on the comparator for equality judgements (e.g. SortedSet) may result in things with the same
  score being considered equal.
