If I have understood the RFC correctly, it talks about SRV RR and not A RR, and as far as I know, there is no RFC updated 1034 and 952 on this aspect. The same thing worked for FreeBSD's portsnap service at the very least, and also Yahoo's domain key, but neither is an A RR having underscore and, for many traditional Internet applications like sendmail, an A RR with underscore is rejected. I have made a change on -CURRENT and is waiting for comments from others to see if it's suitable for MFC, to make it possible to resolve an A RR with underscore symbol, instead of querying it and drop the result, and give the application an opportunity to choose between rejecting or allowing _'s when they are using gethostbyname().
