I know of two Ruby gems that sort LC for you.  There's one Bill Dueber created 
and I hacked a bit:

    https://github.com/billdueber/lc_callnumber

and then there's this more recent one I saw mentioned on Planet Code4Lib a day 
or two ago:

    https://github.com/pulibrary/lcsort

I haven't tried it and don't know how it relates to the first, but if you want a 
Ruby approach, those should help.
