As you want to put new Category attribute under Custom Design tab then you need use tag

'group'.That means when you create attribute then you need to set group Custom Design

See Example:

<?php
$installer = $this;
$installer->startSetup();


$installer->addAttribute("catalog_category", "is_custom_field",  array(
    "type"     => "varchar",
    "backend"  => "",
    "frontend" => "",
    "label"    => "Amit Custom ",
    "input"    => "text",
    "class"    => "",
    "source"   => "",
    "global"   => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE,
    "visible"  => true,
    "required" => false,
    "user_defined"  => false,
    "default" => "",
    "searchable" => false,
    "filterable" => false,
    "comparable" => false,

    "visible_on_front"  => false,
    "unique"     => false,
    "note"       => ""
    'group' => "Custom Design"

    ));
$installer->endSetup();
