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.
