That won't work for whatever sort condition.

I'd probably rather compare the MD5 checksum of the scalar references in the list before and after the sort.

    Sure it will, its comparing memory addresses not data, so the sort condition is irrelevant; only relevant are how much ram you have and how you initialized the array; if the memory addresses aren't sequential before sorting, it won't work.
