wordpress: wp_list_categories order by is not working at all

Context: Using WordPress with jigoshop plugin

I am using wp_list_categories to bring product categories that working well and brings the required list. The only problem is the ordering of the categories. I have used several orderby options (name, ID, slug) but the list order remains still the same as follows:

Tools & Brushes
Makeup Remover & Primer
Powder
Lips
Highlighter
Foundation
Eyes
Concealer
Bronzer
Blush

The jigoshop widget has following code:

$args = array(
    'orderby'       => 'name',
    'show_count'    => $count,
    'hierarchical'  => $is_hierarchial,
    'taxonomy'      => 'product_cat',
    'title_li'      => null,
);
wp_list_categories(apply_filters('widget_product_categories_args', $args));

I am going to replace it by adding filter:

add_filter('widget_product_categories_args','myFun');
function myFun($out){
    .......
    .......
    $args = array(
    'orderby'            => 'name',
    'order'              => 'ASC',
    'style'              => 'list',
    'show_count'         => 0,
    'hide_empty'         => 0,
    'child_of'           => $topMostParent,
    'hierarchical'       => 1,
    'title_li'           => '',
    'current_category'   => $cur_cat,
    'taxonomy'           => $taxonomyName,
);  
return $args;
}

I have tried by deactivating other plugins too but got no effect on result. Please help.
Thanks.
