Rather than creating a list-of-tuples data structure, you might want to use
Python's built-in sorting features:
words=histogram.keys()
words.sort(lambda x,y:cmp(histogram[y],histogram[x]))
for w in words:
    print "%s : %d"%(w,histogram[w])

The above code sorts in decreasing order.  Use cmp(histogram[x],histogram[y])
to sort increasing.
