BIND allows domain names to have underscores.  It objects to non-hostnames
owning A, AAAA or MX records is all.  For example, this is served by BIND:

_jabber._tcp.jabber.isc.org. 7126 IN    SRV     0 0 5269 sprocket.isc.org.

Can I ask what specific problem you're having that would be solved by this?
