Hot damn! This works:

myDoc = app.documents[0];
myPstyles = myDoc.paragraphStyles;
myNstyles = myPstyles.item('Body').nestedStyles;

myNewNstyle = myNstyles.add();

for (i=(myNstyles.length - 1); i>0; i--) {
	myNstyles.item(i).properties = myNstyles.item(i-1).properties;
}
myNstyles[0].appliedCharacterStyle = myDoc.characterStyles.item('Green');
myNstyles[0].delimiter = NestedStyleDelimiters.anyWord;

I added a nested style to the paragraph style 'Body', then, using the for loop, I shuffled the properties down one, then I set the two properties of the first style so that the first word would now be green. (the inclusive and repetition properties were already as I wanted them).

Not as convenient as adding the new style at the beginning of the list right off the bat, but not that much work that it's something to worry about.
