In 1.9.1.0 this problem could be solved through patching in another class Mage_Core_Model_Url_Rewrite_Request/function _processRedirectOptions().
Just add after code

    $targetUrl = $this->_request->getBaseUrl() . '/' . $this->_rewrite->getTargetPath();

    $storeCode = $this->_app->getStore()->getCode();
    if (Mage::getStoreConfig('web/url/use_store') && !empty($storeCode)) {
        $targetUrl = $this->_request->getBaseUrl() . '/' . $storeCode . '/' . $this->_rewrite->getTargetPath();
    }

    if ($this->_rewrite->hasOption('R') || $isPermanentRedirectOption) {

the following

            $queryString = $this->_getQueryString();
            if ($queryString) {
                $targetUrl .= '?'.$queryString;
            }

and make sure 'if' statement keep closed with

           $this->_sendRedirectHeaders($targetUrl, $isPermanentRedirectOption);
    }

I'm sure it's fairly enough because of you don't need to transfer query string for external redirects.

Happy coding
