正如您提到的，我遵循的示例与您发现的示例相同，但对我不起作用，我对roundingSetCollection函数做了很小的改动，如下所示：

public function aroundSetCollection(
  \Magento\Catalog\Block\Product\ProductList\Toolbar $subject,
  \Closure $proceed,
  $collection
) {
  $currentOrder     = $subject->getCurrentOrder();
  $result            = $proceed($collection);

  if($currentOrder) {
    if($currentOrder == 'high_to_low') {
      $collection->setOrder('price', 'desc');
    } else if($currentOrder == 'low_to_high') {
      $collection->setOrder('price', 'asc');
    } else if ($currentOrder == 'created_at') {
      $collection->setOrder('created_at', 'desc');
    }
  }

  return $collection;

}
