storybook: In production, stories do not appear in export order

Describe the bug In production, stories do not appear in export order. Instead, they are sorted alphabetically.

#15574 describes similar behavior and was closed when a fix was released in v6.14.13 and v6.5.0-alpha.17. I’m still experiencing this problem with Storybook 6.5.0-alpha.45, however.

Thank you in advance for your help!! 😄

To Reproduce

1. Clone https://github.com/rdebeasi/storybook-sort-repro

2. Run yarn storybook to start Storybook in dev mode. Stories appear in export order (Story C, Story B, Story A). This is the expected behavior.

3. Run yarn build-storybook && npx serve to start Storybook in production mode. Shows appear in sorted in alphabetical order (Story A, Story B, Story C). This behavior appears to be a bug.
