Ordering a Taxonomy Query loop by custom fileds (Metabox)

Hi guys,
I have a query loop of taxonomies and I can’t figure out how to sort it based on a custom fileds created with Metabox.

I have tried “orderby meta value + custom fields name” and also “orderby meta numeric value + custom fields name”. I pravo with both a “number” and a “text” custom fields. I can’t.

Does anyone have any suggestions?
