I think your question is answered by this part of the documentation:

: The query response is checked against all response policy zones, so two
: or more policy records can be triggered by a response. Because DNS
: responses are rewritten according to at most one policy record, a single
: record encoding an action (other than DISABLED actions) must be chosen.
: Triggers or the records that encode them are chosen for the rewriting in
: the following order:
: 1. Choose the triggered record in the zone that appears first in the
:    response-policy option.
: 2. Prefer CLIENT-IP to QNAME to IP to NSDNAME to NSIP triggers in a
:    single zone.
: 3. Among NSDNAME triggers, prefer the trigger that matches the smallest
:    name under the DNSSEC ordering.
: 4. Among IP or NSIP triggers, prefer the trigger with the longest prefix.
: 5. Among triggers with the same prefix length, prefer the IP or NSIP
:    trigger that matches the smallest IP address.
