A quick grep shows these two spots rely on 'next':

api/v3/CustomSearch.php:  $params['weight']['api.default'] = 'next';
api/v3/ReportTemplate.php:  $params['weight']['api.default'] = 'next';

Those two API' wrap around the OptionValue API. Any idea on how we should update them in tandem with this patch? Perhaps we could just remove those lines?
