Grabbing half the answer from your(?) HTML Purifier thread:

$config = HTMLPurifier_Config::createDefault();
$config->set('CSS.AllowedProperties', 'text-align');
$purifier = new HTMLPurifier($config);

That's the first step. If you want to disallow anything but center as in that thread, you would change the CSS AttrDef for text-align:

$css = $purifier->getCSSDefinition();
$css->info['text-align'] = new HTMLPurifier_AttrDef_Enum(array('center'));

// should allow text-align:center but not text-align:right or the likes:
$purifier->purify(/* ... */);
