I've just tried it and yes, the 'section' variable doesn't create tabs, but its does create sections on the quota view page so it does look as though tabs are not available for module quota views - Sorry.
Below is my test quota code and attached is what it looks like.
hth
<?php
defined('APP_DIR') or exit();
function jrXxxx_quota_config(){
$_tmp = array(
'name' => '1111',
'type' => 'text',
'label' => '1111',
'help' => '1111',
'default' => '1111',
'section' => 'section one',
'validate' => 'core_string'
);
jrProfile_register_quota_setting('jrXxxx', $_tmp);
$_tmp = array(
'name' => '2222',
'type' => 'text',
'label' => '2222',
'help' => '2222',
'default' => '2222',
'section' => 'section two',
'validate' => 'core_string'
);
jrProfile_register_quota_setting('jrXxxx', $_tmp);
$_tmp = array(
'name' => '333',
'type' => 'text',
'label' => '3333',
'help' => '3333',
'default' => '3333',
'section' => 'section two',
'validate' => 'core_string'
);
jrProfile_register_quota_setting('jrXxxx', $_tmp);
return true;
}
