The *_n functions were developed so that 'dimension reordering'
would not be necessary. For
    modelTemp(time,zlev,latitude,longitude)
                0 1 2 3
The correct useage is

  isot = int2p_n_Wrap(modelTemp, depth, tlev, 0,1)

In fact, they are from the "default" palette, and appear to start with index 4 (as per cnRes@gsnSpreadColorStart = 4), and are for the most part every other color from the palette, with a few exceptions. Its as though the palette is not getting set to what you specified. Are you getting any errors/warnings about that?
