Add configuration options for sorting

**Problem**
When working with models, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

No files, tests, or entry points are named. Start by locating the model handling and sorting configuration areas, then clarify the expected configuration options and error-message behavior with the maintainers. Done should include agreed behavior and tests covering sorting and the more descriptive errors.
