With DNSsec the order is only important to generate the
NXT records. There is *no* requirement that they be
transmitted (or stored) in order. However you do need to
be able to find the predecessor of the query name when
answering with NXDOMAIN. i.e. all the servers for the zone
that support DNSSEC need to be able to sort the zone, they
don't require it to be sorted when it is transfered or loaded
from disk initially.
