It's fun trying to figure out what the heck John's code does :)
Split each element of @array on whitespace (/\s+/), re-order, and pass
right like so:
468X60 31472 1.49\031472 468X60 1.49
468X60 31473 2.18\031473 468X60 2.18
180X60 31488 1.39\031488 180X60 1.39
468X60 31476 1.58\031476 468X60 1.58
120X60 33472 2.49\033472 120X60 2.49
468X60 32473 4.38\032473 468X60 4.38
It then sorts the list so we have:
120X60 33472 2.49\033472 120X60 2.49
180X60 31488 1.39\031488 180X60 1.39
468X60 31472 1.49\031472 468X60 1.49
468X60 31473 2.18\031473 468X60 2.18
468X60 31476 1.58\031476 468X60 1.58
468X60 32473 4.38\032473 468X60 4.38
And then, finally, splits on \0 and takes the second part of that line,
which is the part ordered as the OP wanted it:
33472 120X60 2.49
31488 180X60 1.39
31472 468X60 1.49
31473 468X60 2.18
31476 468X60 1.58
32473 468X60 4.38
