Unable to retrieve Order's metafields in Order Status page

[Swathi_]

I am unable to get metafield value associated to an order in the order status page. The liquid works fine to get checkout object values but not order metadata field. Am I missing anything? 

{{order.metafields.custom.images_status.value}}

I need to show a specific section/instructions on Order Status page based on the Order metafield's value. Please help.
