Even if I set a minor value to dns_tls_preference (so higher priority I expect) it still uses UDP.
By reading the doc it seems that higher values of dns_xxx_preference take preference (it's the opposite to NAPTR records "order"). However as I said I'm trying setting the same value for all the transports.
