Sort by float lists

[medwards]

Closes #427

Rationale for this change

No particular reason float types shouldn't have the same support as integers in this case. Booleans are excluded due to not being primitive types.

Note: We don't have any use-cases that would need this so its just a completionist nit so feel free to leave in draft.
