isEqual assertion returns false with two equal complex structures

When comparing two equal, complex structures, the assertion sometimes returns false depending on how those structures get serialized.

By "complex" structure, I mean one with nested structures and arrays, i.e.

I believe the problem lies in the way in which TestBox is serializing the structures, i.e.

This will only create a predictable order of keys for the top level of keys - any nested structures and arrays are still native CFML structures.
