Currently Octave's orient() function does not recognize the "tall" option, and 
the "landscape", "portrait" options do not flip the "papersize" (1x2) vector. 
So there are both a missing feature and a bug.

To do what you want,

# equivalent to "orient tall"
papersize = get (gcf, "papersize"); # presently the paper units must be inches
border = 0.25;
set (gcf, "paperposition", [border, border, (papersize - 2*border)])

# To change orientation
orientation = get (gcf, "paperorientation");
papersize = get (gcf, "papersize");
paperposition = get (gcf, "paperposition");
set (gcf, "paperposition", paperposition([2, 1, 4, 3]);
set (gcf, "papersize", papersize ([2, 1]);
set (gcf, "paperorientation", setdiff ({"landscape", "portrait"}, orientation);

I'll prepare a changeset today.
