I can't answer this one.

At the time of greylisting, the Message-ID is not known.

You'll only know the message-id after the end of the SMTP DATA phase when the
message has already been transfered.

The only data available at the time of greylisting is:

Remote IP
Remote RDNS (if any)
Remote HELO/EHLO string
envelope from (ie: the MAIL FROM command)
envelope recipient (ie: the RCPT TO command).

That's all the information that has been provided by the remote server at the
time milter-greylist decides to greylist or not. You don't know the contents of
any message headers, or the body.
