This has been touch upon several times during the discussions on past
patches.

Essentially, the current patch only arranges that you can specify a sort
order for data.  The system always breaks ties using a binary
comparison.  This could conceivably be changed, but it's a separate
problem.  Some of the necessary investigation work has presumably
already been done in the context of citext.
