Sort values in custom filter element added by meta fields

[naoki-kamatsuka]

I have added a custom filtering factor ‘Size’ by adding product meta field.

but is it possible to reorder elements in ‘Size’?

The order of the custom elements seems strange to me.
I would like to reorder them from top to bottom as Large, Medium, Small, Mini instead of Large, Medium, Mini, Small as in the capture.

Thanks in advance!
