Something like this gives the basis to start from:

        du -sk * | sort -k2 | mklist.awk

where mklist.awk is a short awk script that looks like:

#!/bin/awk -f
BEGIN {
        ## Change LIMIT to whatever -- this is in kilobytes
        LIMIT=680000

        CDCOUNT=1
        SIZE=0
        print " [at] CDROM" CDCOUNT
}
{
        if (SIZE + $1 > LIMIT) {
                SIZE=0
                CDCOUNT++
                print " [at] CDROM" CDCOUNT
        }
        SIZE += $1
        print "./" $2
}
## End of Awk.

Now the output of this can be passed through to something else to create
the ISOs.
