Late answer. Sorry.
You can save your document in Word 2003 (.doc) format and access the legacy WordArt dropdown. In addition, you can create your WordArt in such a document and copy and paste it into a .docx formatted document.

Alternatively, you can have access to these choices including the vertical layout through a custom AutoText gallery in Word 2010 .docx formatted documents. Here is a link to an Add-In that gives the following on the Quick Access Toolbar (QAT). Legacy WordArt Add-In for 2010-2013



This Add-In is macro-free and was developed using tools written by Greg Maxey and Jay Freedman (although they are not responsible for any problems there may be with it).
