Unfortunately, I don't think there is any real alternative to 
cut-and-pasting GtkEntry, renaming it, and adding right 
justification to it; I believe that basically all that is needed
is in gtk_entry_adjust_scroll():

  if (gtk_widget_get_direction (GTK_WIDGET (entry)) == GTK_TEXT_DIR_LTR)
    {
      min_offset = 0;
      max_offset = MAX (min_offset, logical_rect.width / PANGO_SCALE - text_area_width);
    }
  else
    {
      max_offset = logical_rect.width / PANGO_SCALE - text_area_width;
      min_offset = MIN (0, max_offset);
    }

Should be:

  if (gtk_widget_get_direction (GTK_WIDGET (entry)) == GTK_TEXT_DIR_LTR &&
      !right_justified)
    {
      ...
    }

[ Note, if your code isn't [L]GPL, then you'll need to create a separate
  library to hold the cut-and-paste of GtkEntry ]
