This really depends on how the order is build up and how they are identified in html.
I would guess it's a list item, my approach would look something like this.
If I would have the site and see how it looks like it would help figuring out what you want to achieve, but anyways.
So in xpath it would look like this
//li[@item='foo']["2"]
If you would only check the first or last item
//li[@item='foo'][first()]
//li[@item='foo'][last()]
In css which is preferable, since it's faster
css=ul#list li:nth-child(1)
css=ul#list li:nth-child(2)
This should get you started in figuring it out.
