Hierarchical Select and content display order

I've installed/enabled Hierarchical Select and it does just what I need on the form. Unfortunately the results are stored in the reverse order from what I need, i.e. the deepest item is returned first. They are grouped correctly, i.e. version, version, product, version, product, company, but I need them to be company, etc. How do I go about reversing this order? I've read the README for Hierarchical Select and the section on "Rendering hierarchy lineages when viewing content", but I'm pretty new to this and don't really understand what to do. Can someone help me out? Thanks.
