[support] Sorting nodes

Hi to all, Here http://iowalincolnhighway.org/Attractions you can see that the Attractions page is a just basic page, with some listed attractions. Now I have to create new content type, with attraction name, description, image, address, county, google map and/or long/lat coordinates. I know how to create new content type. I just wonder how to sort the nodes? Ideally, it would be sorting by long/lat coordinates from east to west but I’m assuming it’s hard? The most easiest and the fastest way would be by adding “order” field (integer) and manually sort it by the order. Though, it could be PITA to reorder once I have almost hundred nodes… :(

Any suggestions?

Thanks
