You can keep Mootools, or whatever you use... :)

function getStyle(el, prop) {
  var view = document.defaultView;
  if (view && view.getComputedStyle) {
    return view.getComputedStyle(el, null)[prop];
  }
  return el.currentStyle[prop];
}

​function getElementByStyle(style, value, tag)​ {
  var all = document.getElementsByTagName(tag || "*");
  var len = all.length;
  var result = [];
  for ( var i = 0; i < len; i++ ) {
    if ( getStyle(all[i], style) === value )
      result.push(all[i]);
  }
  return result;
}
