From the documentation, it looks like you can’t order by last night. You can sort by ID, nicename or display name. last_name is stored as a meta value, so you may either need to use a custom query or simply retrieve all users and sort via PHP – in both cases, creating your own dropdown.

I know that I can’t do it, which is why I created my post. I need to know How to do it.
No need to get snarky, we are not mind readers, we don’t know what others know unless they care to share it. Rebecca DID tell you how to do it, a custom query or php routine to sort by a value fragment.
First you’ll need to develop a regexp that reliably returns last names from the combined value. Then you can either include it in an ORDERBY mysql statement or use it to build a structured array using one of the array sort functions like asort, ksort, usort, uksort, etc.
From those results, you can easily build your own dropdown.

I don’t know how to do any of that, so if someone could post an example that would be helpful.
Merry Christmas. =) Basic dropdown with a list of all user display names, sorted by last name.
function userDropDownByLastName($echo = true) {
$args = array('who' => 'all_with_meta');
$results = new WP_User_Query($args);
if(!$results) { return false; }
$users = array();
foreach($results->results AS $user) {
$users[$user->last_name] = $user->data;
}
ksort($users);
$return = '';
$return .= "<select>
<option></option>";
foreach($users AS $lastName => $value) {
$return .= "<option value='{$value->display_name}'>{$value->display_name}</option>";
}
$return .= "</select>";
if($echo) {
echo($return);
}
return $return;
}
userDropDownByLastName();
