fu! MyHighlight(match)
if exists("s:prev_no") && s:prev_no + 0 >= a:match+0
let curpos = getpos('.')
call add(w:highlight, matchadd('Error', '\%'. curpos[1]. 'l'.
a:match. '$'))
endif
let s:prev_no = a:match
endfu

fu! CheckOrder()
if exists("w:highlight")
sil! call map(w:highlight, 'matchdelete(v:val)')
endif
let w:highlight = []
%s/\d\+$/\=MyHighlight(submatch(0))/n
unlet! s:prev_no
endfu


save that to a file, source it and then :call CheckOrder() in your file.

Best,
Christian
