scripts: ctx.py: Only sort children layers if explicitly requested

- Sorting struct fields by name? Eh, that's not a big deal.
- Sorting function params by name? Okay, that's really annoying.

This compromises by sorting only the top-level results by name, and
leaving recursive results in the order returned by collect by default.
Recursive results should usually have a well-defined order.

This should be extendable to the other result scripts as well.
