Not htaccess, but another way could be to use PHP to redirect:
<?php
$redirectlist = array('register','login','myaccount');
if (in_array($_GET['p'], $redirectlist) && strtolower($_SERVER['HTTPS']) != 'on') {
exit(header("location: https://{$_SERVER['SERVER_NAME']}{$_SERVER['REQUEST_URI']}"));
}
?>
, , , , htaccess. PHP- , (. header()).
