The script concerned is /etc/event.d/rcS (and /etc/event.d/rcS-sulogin - 
both are owned by the initscripts RPM.

They do this:
runlevel=$(/bin/awk -F ':' '$3 == "initdefault" { print $2 }' /etc/inittab)

i.e. they don't ignore the line if $1 contains ; or #

They should probably do something more like:
runlevel=$(/bin/awk -F ':' '($3 == "initdefault") && ($1 !~ /(#|;)/) { 
print $2 }' /etc/inittab)

I've assumed that # and ; are comments and aren't allowed in the 
runlevel descriptions.
