Why doesn't a symbolic link work for this purpose?

I think you should be able to do

  cd /usr/local/bin
  ln -s /Applications/Octave.app/Contents/Resources/bin/octave

and then create a script with the contents (say doit):

  #! /usr/local/bin/octave -qf
  1 + 1

and then

  chmod a+x doit
  ./doit

Or you can avoid the symbolic link if you start your scripts with

  #! /Applications/Octave.app/Contents/Resources/bin/octave -qf

but people will have to change that when they run your code on a
system that has Octave in a different directory.

If you don't know where Octave will be installed and you want your
scripts to be somewhat more portable, you could maybe use something
like

  #! /usr/bin/env octave

instead, but unfortunately, adding arguments after the octave command
doesn't work as you might expect when it is used as a #! line.
