The programs are started or stopped in the order of the names. S01 comes
before S09 when starting, and K05 comes before K25 when stopping. (S is
for Start, and K is for Kill or stop.) Files not starting with S or K are
ignored.
When entring a run level, first all the files starting with K are run,
then all the files starting with S are run.
Now for managing the symlinks, there is a nice program called chkconfig
that will create the symlinks for any properly formatted file in
/etc/rc.d/init.d, as well as disabling any service. It uses the
# chkconfig: LLLL Start Stop where LLLL are the levels to run the service,
Start is the value for the S link, and Stop is the value for the K link.
ie for sendmail, the line is:
# chkconfig: 2345 80 30
Run when at runlevels 2, 3, 4, and 5.

man chkconfig information on what it will do.
