Failover domain priority doesn't get honoured when relocating service manually with `clusvcadm` command

Issue

Cluster service is configured to run in following failover domain:

<failoverdomain name="failoverXYZ" nofailback="1" ordered="1" restricted="0">
                                <failoverdomainnode name="node1" priority="1"/>
                                <failoverdomainnode name="node2" priority="2"/>
                                <failoverdomainnode name="node3" priority="3"/>
</failoverdomain>

Based on the above configuration the service should primarily run on node1 and should relocate to node 2 when relocation is required. When clusvcadm -r <service> is executed sometimes service relocates to node3 which is not expected as per the priority . Why service relocates randomly?
