I've been fighting with this one for a bit and it seems that there has been a regression in CentOS 6 as far as anaconda ignoring the selinux --disabled directive. This appears to have first appeared in RHEL 4.8, and then re-appeared in RHEL 5.6.
Now with the previous releases you would just add the sed statement to your %post directive to disable it.
sed -i -e 's/\(^SELINUX=\).*$/\1permissive/' /etc/selinux/config
The problem I'm running into is that new in RHEL/CentOS 6 is the fact that they are setting file system attributes by default so you now have to go and clear those.
I tried running the following command to strip those attributes in my %post section, but it does not have any effect.
find . -exec setfattr -x security.selinux {} \;
