If you add a RescoringMatchScorer to a SortOptions as in the following code:

sort_opts = search.SortOptions(match_scorer=search.RescoringMatchScorer())

then, this will sort the documents in descending score order. The scores will be positive. If you want to sort in ascending order, then use the following code:

sort_opts = search.SortOptions(match_scorer=search.RescoringMatchScorer(),
    expressions=[search.SortExpression(
        expression='_score', direction=search.SortExpression.ASCENDING,
        default_value=0.0)])

The scores in this case will be negative.
