When your RR set is cached, the cacging server responds with its own RRset
ordering policy.

conclusion: your auth server policies don't/can't determine how its records
are handled by caching servers.
>s there any way to influence this behavior from the authoritative server
there is nothing in the DNS protocol for the auth server to
express/transmit it policies to other servers.
