How to sort trade offers?

Question

1C-Bitrix

In the "catalog" component, trade offers are sorted by the "Weight" property (type: list). The problem is that the values ​​of this property seem to be treated as strings rather than numbers and are sorted alphabetically, thus resulting in:

1000
450
5000

instead of:

450
1000
5000

How can I fix the problem?

Answer 1

As an option, customize the template and re-sort inside it.
