Lists like views will not be passed through hook_node_access(), as this would create too much overhead. Views does a query on the database to get the results. hook_node_access() is run in PHP, so these won't work (easily/well/efficently) together.
To deal with lists, you will need to create a grant system, using hook_node_access_records() and ...

/**
* Implements hook_preprocess_HOOK().
*/
function ...
