Thank you for writing Extension:Sort. It sorts "See also" lists fine, which was a use case I had in mind.
Andre Klapper is unhappy[*] sorts negative numbers incorrectly. I don't know why he's concerned about numeric sorting, but I am reporting his concern anyway.
Here are some more details: The extension sorts negative numbers incorrectly because it uses PHP's natsort() "natural" sorting function, which also sorts negative numbers incorrectly. For example: natsort(7, 12, -13, 2, 100, 5, 1, -2, 23, 3, 6, 4) returns [ -2, -13, 1, 2, 3, 4, 5, 6, 7, 12, 23, 100 ].
Andre would like you to modify the extension to include a mode for sorting lists composed of both positive and negative numbers. Perhaps this mode could use sort() or asort() instead.[**]
By the way, Andre, why do you want numeric sorting?
