Actually, the numbering scheme follows the old BASIC numbering for a few
reasons:

First, unless you leave room between numbers, you can't easily insert anything
between entries without renumbering (renaming) a bunch of stuff.

Second, I think the shell sorting via the '*' is lexographicly sorted (i.e. '10'
comes before '3') rather than numericly sorted as used in the /etc/rc.d/rc
script.

Third, the /etc/rc.d/rc script actually uses the shell pattern '??' which
will only match two characters (which presumably should be [0-9]).

see the scripts in /ect/rc.d - specifcicly rc, rc.local, and rc.sysinit 
they're not all that hard to read.  the manpage on bash explains alot
of it (though that's a dry way to learn shell scripting - try the blowfish
book instead).

you're welcome, thanks for the plug to plug :)

try starting/stopping each independantly once you get into runlevel3
if you can start them manually, then you _should_ be able to get them to
start vi the rc script(s) at boot time.
