Cut the price, spend time advertising (through social networks)... jump 50 places all for free.
(Aside: Another thing that I can't check because I have no access to Itunes but a jump from say 1000-950 is not amazing neither is 700-650 so depending on where their app is placed and how many apps there are I don't know that this means anything.)
