### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #61596
Problem Summary:
Pick #61596 to branch-4.0.
When a column has multiple inverted indexes (e.g., different analyzers),
select_best_reader could return different readers depending on
std::unordered_map iteration order, causing non-deterministic behavior. This
fix sorts candidate readers by index_id to ensure deterministic selection.
