Directory Listings Sorted

I have a website with the Directory plugin.

On the page listings the listings do not appear to be in any order.

Is there a way to sort these?

I asked a similar question about sorting by a Custom Field but that did not end up being what the client wants.

They just want to sort by the Title of the listing.

Here's the website and page:
