Hmm, I gave you an easy solution in a another mail.

Instead of thoose single letter <reference type>, why not search
for the device attribute instead, like Capacitor, Resistor etc.

Why not use (or the geda equiv.):
$ cat attribs
device
footprint
value
$ lepton-netlist -g bom styrkort.sch
$ grep Capacitor output.net | head -3
3C1 Capacitor ipc7351b_2012Ar.fp 1u
3C2 Capacitor ipc7351b_2012Ar.fp 10n
3C3 Capacitor ipc7351b_2012Ar.fp 1u
$ echo `grep Capacitor output.net | cut -f 1 | sort `

My guess is that your program doesn't provide anything new.
