Scoring while sorting
What is the point to calculate score if the result set is going to be sorted
by some field?
Is it ok to replace several terms query (a OR b OR c) with MatchAllQuery and
RangeFilters (from a to a, from b to b, from c to c) if sorting is needed?
Won't it be faster?

Yes.
Solr actually has an optional optimization where a query with a sort
without a score component can use a cached filter and re-sort that.
