Fine. I documented the ones I knew about... *grumble*

+TAG ATTRIBUTES
 
     The mt:Order tag takes the following optional attributes:
 
     *   sort_order
-    *   natural
-    *   shuffle
-    *   by
-    *   lastn or limit
+        Valid values are "ascend" and "descend" 
+
+    *   natural - Turns on natural sorting which is adaptive
+          to the content being ordered.  This is useful, for
+          example, if you're trying to achieve a numeric sort
+          instead of an alphabetic sort.
+
+    *   shuffle - Orders items randomly. The exact opposite of
+          order we'll note.  Indeed, chaos from Order.
+
+    *   by - ?????
+
+    *   lastn or limit - Limits the number of post-order list
+          items published to the first N where N is the value
+          of the attribute.
 
     The mt:OrderItem tag takes the following optional attribute:
 
-    *   pin
+    *   pin - This attribute allows you to inject an item directly
+          at a specific ordinal spot (such as 0 for first, 5 to
+          become item #6, or -1 for last) 
 
     (While use of the above should be obvious, a better description
     will hopefully be provided by the plugin author...)
