I think this has to do with the "1:1" actuation ratio on the sram derailleurs-- it takes more cable pull to make a shift with the sram. If you want to use a bar-end shifter with the stock derailleur, you'll have to use it in friction mode, and possibly grind off some material to make it cover the whole range.
