> (1) keeping the order consistent throughout an application

Not even just an application. The whole phone needs to be consistent. Every app in it. Otherwise it's just repeatedly discovering and forgetting how to use each and every app's unique interpretation of what their average user wants and what their average user thinks is intuitive.

I mostly agree, and that is why I mentioned that you should follow the general design guidelines for your respective platform. However, when creating a web app, general guidelines are more "implied."

The biggest reason why consistency is more important than following platform guidelines is for cross-platform apps available on multiple devices that have different platform design guidelines. It's obviously not feasible (and I would argue not user-friendly either) to switch the order of action controls for the same app on different devices, especially when the app is available via a web interface as well as native.
