I recently did some work on the sort command for LiveCode 8 to optimize
it's performance:

The improvements were dramatic. Indeed, the new approach is actually
much better than it was prior to 7.0 as it ensures it only computes
certain information it needs once, and operates on a much smaller
intermediate representation.
I asked Seb to take some timings of the stack you provided in different
versions. Here is what he found:
6.7.7-rc-2 xSortListe 56ms - sort full list
6.7.7-rc-2 xSortListe 27ms - sort list items with 'a'
7.1.0-rc-3 xSortListe 596ms - sort full list
7.1.0-rc-3 xSortListe 293ms - sort list items with 'a'
8.0.0-dp-5 xSortListe 44ms - sort full list
8.0.0-dp-5 xSortListe 26ms - sort list items with 'a'
Freakin' awesome, Mark - thanks!
Any chance some of what was learned there can be applied to lineoffset?
The performance difference with that function is similar to what we saw
with the sort command (about ten-fold), so I'm hoping a fix can be as
achievable.
