I know it works for functions. I haven't tried it for scripts.

plot(x,y,';legend entry;');
OR
download legend.m (and supporting functions) from octave-forge
http://octave.sf.net.
The former is definitely preferred. You will also notice that titles
and labels will not be showing up properly. Unless you have an octave
flag set (automatic_replot IIRC), titles and labels will not be added
to the plot. The other thing you will notice is that titles and labels
are not cleared between plots.
