Thanks for these links (++). Very interesting.

that GRT is tricky is shown by this necropost (by me!) pointing out a bug that lay undetected for 18 months in a node with 264 rep!

In reading through what I presume to be the original GRT paper I was directed to Sort::Maker by Uri Guttman himself. It appears that this module is designed to help abstract away such trickiness and would likely be the approach I would take for such tasks in future. YMMV, of course.
