Add TypeScript types for utils

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

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

**Priority**: Low/Medium

Start by locating the utils and handler code referenced by the issue, then inspect how handler options and existing types are defined. Determine where sorting is configured and what defaults are appropriate; done means handlers support configurable sorting with sensible defaults and the related behavior is verified.
