How do I sort ascending string just numbers?

Velo: The ascending() function refines a WixDataQuery or WixDataSort to sort in ascending order of the specified properties. If a property contains a number as a String, that value will be sorted alphabetically and not numerically. Items that do not have a value for the specified sort property are ranked lowest.
