Could you add a method to switch between sorting and non-sorting behavior. The non-sorting version should not use more resources than the original BooleanScorer.

Otherwise next() might return a higher document number than skipTo() would skip to, ie. a lower document number would not be scored at all. In that case the implementation of skipTo can also be simplified somewhat because it would only have to delete from the beginning of the valid bucket list. I think a version of BooleanScorer modified with this patch could be used as a BooleanSubScorer. As a top level scorer, BooleanScorer is difficult to beat in performance for non required clauses, and on the top level it is not a problem that documents are not processed strictly in order, normally they will be used in a Hits that presents them in another other anyway. For a non top level scorer, or when the document order should be followed strictly, the patched version could be used as BooleanSubScorer, or the DisjunctionScorer posted earlier could be used. Below top level, DisjunctionScorer could be faster because it never works ahead into a bucket list. A strict document order would also be an advantage when creating an IterFilter from a BooleanQuery.
