Please, do 
load(itensor);
a([i],[n],j);
show(%)$

Viktor says that he already fixed it cvs. Yet another bug. The following did 
work for me two days ago.
plot3d(float(aai[2](o,beta)),[o,0.01,10.],[beta,0.01,10.],[gnuplot_pm3d, 
true],[gnuplot_preamble, "set pm3d at b"]);

Now it complains about option "set pm3d at b". You can simply try 
sin(o)cos(beta) instead float(aai[2](o,beta)).
