I was just about to suggest something similar. I would probably use  
anonymous functions here - same effect, a little tighter code:

self.scaleDict = {
     'x 1': lambda x: x,
     'x 10': lambda x: x * 10,
     ...
     'x log 10': lambda x: math.log(x, 10),
     'x log 2': lambda x: math.log(x, 2),
     'x log e': lambda x: math.log(x),
}

self.scaleDict[key](x)
