The customer asked how to order the results in the view based on the custom field having values like Platinum, Diamond, Gold, etc.
Solution:
Recommend adding the custom field as a select type field, where the options (e.g. Platinum, Diamond, Gold, Silver, etc) have the numeric values in the required order (e.g. 1, 2, 3, 4, etc).
This will allow selecting this field in the view's "Ordering" settings and the results will be ordered, accordingly.
