i guess etiennes solution is the more professionell one, nevertheless i
worked out an even dirtier solution - but i think it works:

--
a=['adog';'along';'aapple'];
s=toascii(a);
n=columns(s);
for i= n:-1:1
  [so,in]= sort(s(:,i));
  s=s(in,:);
endfor
s=setstr(s)
--
yields...
--
octave:2> s
s =

aapple
adog
along
--
