If working with attributes those are not always available instantly (e.g. for freshly created models).

As expansion on Ayobami Opeyemi's answer you should be able to use Collection's sortBy if you force the attribute to evaluate by calling its function directly:

$products = Product::all();
$products = $products->sortBy(function($product){
    return $product->getTotalAttribute();
});
