Why did you copy the system to harddisk then if you don't plan to change

Can you setup Lilo to boot your installed Knoppix System? Running
Knoppix from harddisk is not a perfect, but a convenient way to
deduce the file sorting order from the access dates of the files,
rather than to guess which files are accessed in which sequence (which
would also be possible).

Using a sortfile from a different system will almost certainly make
yours slower, because files are accessed in different sequence which
leads to a lot of laser movement (which is the most time-consuming part
on a CD-Rom).

I can send you the file next time I'm working on the mastering system,
but I don't think it will make access times better once you changed some
stuff in your version, especially libraries.
