CentOS does something spiffy to include a repo to read off the dvd media.  I'm sure you could tweak it for Scientific Linux.  AFAIK, you cannot restart the ananconda installer, but you can 'yum install' or 'yum groupinstall' things off the dvd media without being on the network.  Please read the comments in their file below carefully for usage examples.


# CentOS-Media.repo
#
# This repo is used to mount the default locations for a CDROM / DVD on
#  CentOS-6.  You can use this repo and yum to install items directly off the
#  DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos too:
#  yum --enablerepo=c6-media [command]
#
# or for ONLY the media repo, do this:
#
#  yum --disablerepo=\* --enablerepo=c6-media [command]
