Unfortunately, according to official Unity docs, automatically opening in VS Express is not supported:

Unity’s VisualStudio integration has two components:

  1. Unity creating and maintaining VisualStudio project files. Works with Express and with Profesional.

  2. Unity automatically opening VisualStudio when you doubleclick on a script, or error in Unity. Works with Professional only.

You can change it in default program. Open Default Programs > Associate File Types > Search extention of your file format and change it to Visual Studio. Maybe work on any version.

This apparently can’t be done with Visual Studio Express, but there is now another free version of Visual Studio, Visual Studio Community Edition. Using that, you can get full integration with Unity.
