AFAIR theres not a way in the resourceinstaller itself. Looking at the components\resourceinstaller\ResourceInstaller.vb file, I see it's just grabing a list of files in the directory via Directory.GetFiles. As far as I remember, that returns an alphabetical list of files, so you could add a numeric order to your zip file name, as it's the DNN file that will specify the name within DNN e.g. two files called b.zip and a.zip must be installed in that order, so change their names to 1_b.zip and 2_a.zip. You can also package multiple module definitions within a single zip, and specify their order via the .dnn file.
