The reason a scroll of genocide is found so infrequently is that
the program is set up with weights for each type of scroll (as well
as for each type of potion, ring, staff/wand/rod, and armor). For
instance, my version has sixteen types of scrolls (yours probably
does too, if it has genocide, one of the more recent additions).
Of those sixteen, genocide occurs only 1 percent of the time while
identify is allocated 21 percent.
As far as a maximum number of times a certain type of object can
show up in a game, I know of no such thing. Except for food being
more likely than normal when you haven't found any in a while, the
choice of things is completely random.
