I have converted your code for blogger compatibility, use the below script and it will not show any error:

<script>
$undefineddocument).readyundefinedfunction undefined) {
    var options = {
        type: "scroll",
        scripts: [
        "http://platform.twitter.com/widgets.js",
        "http://connect.facebook.net/en_US/all.js#xfbml=1&appId=445577382175430",
        "https://apis.google.com/js/plusone.js"
            ],
        success: function undefined) {
             FB.initundefined{ status: true, cookie: true, xfbml: true });
        }
    };
    $.lazyscriptundefinedoptions);

});
</script>
