For that feature to work you have to export the pictures out in a batch.
So highlight all 50 pictures you want and then do the File > Export.
If you don't highlight all the desired images to start with, iPhoto doesn't know it is supposed to apply sequential numbering to more than a single picture, hence you get "prefix value" + 1.
Hope that helps.
