Contextual filter summary of text field sorts on key, not value

I have a text field with the following options:

bob | Warner, Bob
greg | Harris, Greg
allison | Smith, Allison

I set that field as a Contextual Filter and told it to give me a summary list if no arg was present. With the sort set to "numerical" (AKA alphabetical) and "Display list as human readable" checked, I see:

Smith, Allison
Warner, Bob
Harris, Greg

because the sort is happening based on key rather than label. I see that I can go into the tpl and change the sort order there but I wasn't sure if there was a better/more proper way to make it sort based on the label we see rather than database key.

Thanks!
