Extra|Sort Alphanumerically 0-9, A-Z works just like Extra|Sort Alphabetically A-Z, except that it sorts numbers logically. When the text contains numbers that consist of multiple digits, the numbers are compared as a whole. So “A4” sorts before “A10” because 4 is less than 10. This sort order is also known as “natural sort”.
