I just realized that this is because the keyframes' handles in my .blend file are 'Auto Clamped'. Equalize Handles does not work with 'Auto Clamped', 'Vector', and 'Automatic 'handles.

As I said in patch, I don't know much about workflows involved, so not sure if this should be considered as a bug if code works correctly in currenct state. But since you submitted patch, I guess I will confirm. You don't need to create bug report to submit patch.

@Richard Antalik (ISS) Thank you for the tip. I created the bug report initially because I didn't think I'd have the time to submit a patch.
