Actually, it's not that difficult. It would take a minor reworking to make it more robust, but someone should be able to get by with changing line 194 of plugin.py from:

for id, href in self.bk1.text_iter():

to:

for id, linear, href in self.bk1.spine_iter():

And then commenting out line 199 (plugin.py again) that does the sorting.
From:

self.cbXhtmlList=self.natural_sort(self.cbXhtmlList) #Sort the list of images

to:

#self.cbXhtmlList=self.natural_sort(self.cbXhtmlList) #Sort the list of images
