CentOS 5 uses SYSV initscripts, a template is provided in the
scripts directory of the sslh package. Yes, you have to install
the  rc-script manually and use chkconfig to enable it.
What else is not working?

Off-topic note for CentOS 6:
CentOS 6 has switched (as upstream) to upstart. So you'd need to
write an upstart init-file and put it into /etc/init.
See "man 5 init" or RHEL documentation for upstart.

It is only sslh which listens on port 443 if configured to do so,
not ssh or openvpn which both listen on their own respective ports.

You can only bind a single service to a specific port/protocol
pair, e.g. 443/tcp to sslh.

sslh will accept connections on the port configured by --listen
and forward it to the ports configured with --ssh and --openvpn,
e.g. with default ports:

sslh --listen 0.0.0.0:443 --ssh localhost:22 --openvpn localhost:1194
