Improve lib performance

**Description**
Currently handlers lacks proper sorting support.

**Proposed solution**
Add configurable sorting with sensible defaults.

**Priority**: Low/Medium

Start by locating the handlers and library code referenced by the issue, then inspect how results are currently ordered. Clarify the configurable sorting options and sensible defaults, and use the repository's relevant checks to verify consistent handler ordering.
