This is very easy to do. Open your build definition and go to the "Process" page. Then under the "3. Advanced" group you have a property called "MSBuild Arguments". Place the parameter there with the following syntax "/p:VisualStudioVersion=12.0". Of course without the quotes. If you have more parameters, separate them with a space and not a comma.
