You might be going about it wrong. A user can, in Finder's Get Info window, set the application they prefer for all files of a given "type". On my system I've set some text file types to always open in TextMate, for example. TextMate the app provides custom file icons for all the file types it can save in. After making this change in Finder's get info windows, all files of that type will have an icon that has been provided by TextMate and registered with a UTI.
At the end of the day, a user or another UTI more specific than yours may set the file icon regardless of what you want it to be.
