No, there's no reasonable ordering going on.

If it were ordered by ordinal values, "/" is 47 and " " is 32, so "1 in" would come before "1/2 in".

It's not alphabetized by letter word. Because while "Eight" comes before "Four", "Specialty" would come before "Three".

No matter which way you attempt to order it, something is out of order.

Softtalker probably got it right. This is some default or id sort.
