I know Scribus is not meant to edit text like a text editor but could something like TinyMCE be incorporated into scribus as a plugin
http://tinymce.moxiecode.com/ not sure if is possible as TinyMCE is for web stuff but there might be somethig similar out there. If you do this as a plugin you preserve Scribus as a layout program but allow individuals to add that bit axtra if they wish to. Just a thought.
