Sort code needs a tiny little tweak

Wonderful module! Makes modules like Reference Views reallly useful.

However, I couldn't get the sort working (no errors, just no change) until i tweaked the module's views_sort_by_arg_order_handler_sort.inc file. Here's my hand-made patch...

function query() {
    // retrive options
-    $arg_to_use = $this->options['argument_number'];
+    $arg_to_use = $this->options['argument_number'] ? $this->options['argument_number'] : 0 ;
    $inherit_type = $this->options['inherit_type'];

I'm on D6.22, Views 3.0-rc2.
