Change order of Profile module Categories on new account page

I've installed the Profiles module so that I can add fields to the register form for a new user (e.g., first and last name, address, telephone). The fields are categorized into Contact Information and Personal Information. On the form, Personal Information is sorting below Contact Information, I presume based on it's name, but I need to reverse that.

Is the only way to accomplish that to use a custom .tpl.php page to control the building of the form?
