The number is the order / sequence in which the services are either
started and stopped. So if you for instance have Sendmail starting and a
milter application, it is essential that the milter is started before
Sendmail, so that Sendmail finds the milter socket file when it start.
Having Sendmail start value of 80 you need a lower value for the milter,
i.e. 75. This would then for instance be

/etc/rc.d/rc3.d/S75milter-bcc
/etc/rc.d/rc3.d/S80Sendmail

See for instance:
