開始行が mxml だとマズイのかな？

syntaxhighlighter.php に追加しただけではダメなのか。

// Register some popular third-party brushes
wp_register_script( 'syntaxhighlighter-brush-mxml',       plugins_url('syntaxhighlighter/third-party-brushes/shBrushMxml.js'),       array('syntaxhighlighter-core'), '20100428'     );
// added for mxml

本家の ver.1.5.1 でないと働かないのかなあ … Another Lint で怒られるので xml に戻す。

CSS は

/* Website Title
---------------*/

div#header p.siteName {
    margin: 25px 60px 10px;
    line-height: 1;
    font-size: 144%;
    font-weight: bold;
    text-indent: -9999px;
    height: 58px;
    width: 285px;
    background: url(images/selatan.png) no-repeat left top;
}

div#header p.siteName a {
    text-decoration: none;
    color: #417698;
    display: block;
    height: 58px;
    width: 285px;
    overflow: hidden;
}

div#header p.siteName a:hover {
    color: #000;
}

div#header p.siteName a:focus {
    outline: none;
}

php はどうだろう。

<?php
$cwd = dirname(__FILE__);
$dir = mb_substr( $cwd, 0, mb_strrpos($cwd, 'wp-content'));

require_once($dir.'wp-config.php');

$config = get_option('vicuna_config');

if (!isset($config['skin'])) {
    $config['skin'] = 'style-vega';
    update_option('vicuna_config', $config);
}
$skin = $config['skin'];
header("Content-Type: text/css");
?>
@charset "utf-8";

@import url(<?php echo $skin; ?>/import.css);
