Better still, create an errands context and make CVS a subcontext of errands.

Then you can look at CVS-related tasks when you're going to just CVS or look at all of your errands if you're headed out and thinking about doing more than one thing.

Then anything you need to get at CVS you put in the CVS context, including your scrip. Subcontexts are really useful especially for errands since you can classify something as an errand and further classify it by exactly where you need to go. That way you can look at all of your errands easily (just look at the errands context) and you can easily choose to look at only the errands that currently interest you (click on the CVS context). Set up a subcontext under errands for any store you frequently visit.

I honestly suspect that errands were the primary reason Omni put subcontexts in OmniFocus; probably what they were thinking of when they designed the feature.
