Given this from RFC2821:
Lower numbers are more preferred than higher
ones. If there are multiple destinations with the same preference
and there is no clear reason to favor one (e.g., by recognition of an
easily-reached address), then the sender-SMTP MUST randomize them to
spread the load across multiple mail exchangers for a specific
organization.
it rather seems that randomizing equal-weight MX records at the name server
level is sort of... pointless.
