Split MS Word 2008 Document in multiple files

I’m not very familiar with scripting in MS Word but I’m trying to split a doc that uses a text string as ‘delimiter’ (let’s say the delimiter is “$$$$”. Now I know I can do it with applescript’s item delimiters but I don’t want to loose text formatting (bolded words, underlined etc.) Is there a way to do it? I’ve checked a little bit the word 2008 script dictionary and saw there’s a possibility of creating a text range, could this help?

Model: iBook
Browser: Safari 523.12
Operating System: Mac OS X (10.4)

I’m not familiar with Word 2008 (still running Word X), but is there an AppleScript dictionary instruction for inserting a page break? You could replace $$$$ with a page break.
