I did this differently. In an ftplugin file for "qf" type, I actually store off the current window number, call ":copen", and check to see whether the current window number is still the same. Note you need to have a guard variable to prevent recursion.

if &buftype=='quickfix'
if !exists('s:processing')
let listbufnr = bufnr("%")
let numwindows = winnr('$')
let curwin = winnr()
let s:processing = 1
copen
call setbufvar(listbufnr, 'errorlist_type', (curwin == winnr() ? quickfix' : 'location'))
" close the quickfix list if it was closed when we began
if numwindows != winnr('$')
cclose
endif
" return to quickfix/location list
exe curwin 'wincmd w'
unlet s:processing
endif
endif

Now b:errorlist_type holds the type of quickfix list.
