Sort data by number in cell containing number sometimes followed by text

I'm working on a shopping list with aisle numbers in Google Sheets and the aisle numbers can be digits alone or digits followed by a letter.

For example 1, 2, 3, 3, 4, 6A, 8, 19B, etc

I want to sort by aisle number but Sheets will sort 6A after 19B.

For example, 1, 2, 3, 3, 4, 8, 19B, 6A, etc

How can I make it sort by aisle number correctly?
