try this one may be it will help you for the filter and may resolve your sorting ...

protected function _filterStoreCondition($collection, $column)
    if (!$value = $column->getFilter()->getValue()) {

Hmm I think You have to use this code and default sorting will work for magento $this->setUseAjax(false);
