From within Flash Catalyst, the answer is unfortunately no. However, you can add this functionality with Flash Builder. I built a demo in Flash Catalyst 1.0, so instead of a tab bar, I have 3 buttons that jump to different app icons in the list.
The core of the code is two lines: setting the selectedIndex of the list (apps.selectedIndex = 3;). Note the list has an id of 'apps'. And setting apps.ensureIndexIsVisible(3); That line will cause the list to jump to that index. That is all you need to get the base functionality working
You might something a little visually appealing, so take a look at this post:

Thanks, Chris, I appreciate all of your insight. While Flash Catalyst is a
really cool program and has a lot of potential, it seems that there are a
lot of things that should be considered simple that are unavailable for
those looking to use Catalyst only.
I'm hoping, like other Adobe products, that this program turns into
something even more amazing in the future.
I think it will ;). You must also remember what Flash Catalyst's role is in the ecosystem. It's main goal is to help create UIs and interactions for use in Flash Builder, so at some point it will be easier and smarter to have the functionality be done in Flash Builder. It has a lot of power to do a lot of things without 'code', but at some point it will hit it's limits.
