I would prefer if the wording didn't require that order of listing is
required to indicate a necessary order of preference. Thus, I suggest the
following wording:

The order of elements in the "links" array *MAY be read as indicating*
an order of preference.

The idea is to permit readers to infer order of preference, and to
allow writers to express that order, without requiring that a
preferred order be determined or expressed. Where there is no
preferred order, there will be no harm. Where there is a preferred
order, the right thing will happen.
