90% of PHP-Array TSFE isn't generated at the moment the typoscript is parsed, so it doesn't work. The only option to achieve this is to use a userfunc.
A quick-and-dirty userfunc (which doesn't take into account workspaces/versioning) could be:

function user_isTranslationMissing() {
	$pid = (int)$_GET['id'];
	$lang = (int)$_GET['L'];
	if (($pid < 1) || ($lang < 1)) return(false);
    $query = "SELECT P.uid,P.title AS title_orig,L.title,L.sys_language_uid FROM pages AS P INNER JOIN pages_language_overlay AS L ON (L.pid = P.uid) WHERE L.hidden=0 AND L.deleted=0 AND P.hidden = 0 AND P.deleted= 0 AND L.sys_language_uid = ".$lang." AND L.pid = ".$pid;
		
	if (!$result = $GLOBALS['TYPO3_DB']->sql_query($query)) {
		return(false);
	}
	while ($rowtemp = mysql_fetch_assoc($result)) {
		return(false);
	}
	return(true);
}

Just added this for reference if this thread comes up in search results - improvements to this function are welcome.
