What does it mean to sort "1,2,3,4,5" by 12?
Maybe it should be sort items of x numeric by random(10000)
Yes! Sorry about that.
I think sort by 12 effectively means to associate 12 with each item and then sort by the associated value. The sort by random(10000) would then mean to associate a random value with each item and sort by that. The sort by char -1 or each would associate the last char of each item with the item and sort by that.
I don't know if it actually implemented that way; it might be the sorting expression is evaluated repeatedly with each comparison. Maybe one can run a test with a side effect (say counting) to find out.
