Trouble with default sorting (numbers are out of order)

Hey, I’m having an issue with the default sorting option for products.

It’s sorting alphabetically, which I like, but when numbers are added to the product name the sorting gets all mixed up.

For example:
Say I have 11 different photo prints of 11 different Roses.
My titles are like this:
Rose print (No. 1), Rose print (No. 2), Rose print (No. 3), etc.

Instead of that going in number order (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11),
it goes in an order based on the first number (1, 10, 11, then 2, 3, 4, 5, 6, 7, 8, 9)

So, how do I change the sort order from going like this (the wrong order):
Rose print (No. 1), Rose print (No. 10), Rose print (No. 11), Rose print (No. 2) (etc.)

To this (the right order):
Rose print (No. 1), Rose print (No. 2), Rose print (No. 3), Rose print (No. 4) (etc.)

???

Thanks.
