Good question. The draft hadn't covered that. I've now fixed the spec to 
say that the order is important in one respect: the first <link>, <a>, or 
<area> element whose rel="" attribute has the keyword "feed" (which might 
also be implied by rel=alternate in certain cases) is defined to be the 
default syndication feed for autodiscovery purposes.

Currently, the location of the link is irrelevant (except for the first 
one being the default). However, different links with different href="" 
attributes aren't "equivalent"; they point to different documents. They 
can also have different titles (title=""), languages (hreflang=""), and 
preferred media (media="").

I hope this helps. If you have any other feedback, or if you'd like the 
spec changed in any way, please let us know. I am very interested in 
addressing any requirements the Atom community may have.
