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

plot(x,y,';legend entry;');


download legend.m (and supporting functions) from octave-forge  

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.
