Define before invoking and make sure the first non-comment token in
the file is not the keyword "function".  The following should work.

  #!/usr/bin/octave -qH

  1; # not a function file.

  function test1(...)
     argv
  endfunction

  function test2(...)
    argv
  endfunction

  type=str2num(nth(argv,1));

  if type == 1
     test1(argv);
  else
     test2(argv);
  endif
