I think, powerdns supports "basic RoundRobin", but IIRC is it not allowed
to have a CNAME RR and an additional other RR for the same Name ...

Here, you have more than one CNAME RR for the same name. Bind9 in default
configuration will also reject a zone, when these entries are part of the
zonefile (the error-message will be "CNAME and other DATA" or something
similar). If there is a CNAME RR for a name, there really shouldn't be
*any* *other* Record for this name (neither CNAME nor NS nor MX nor any
other Records: CNAME is an "alias" for another Name,all other records
for this host should be for the name, the CNAME RR points to).
