All you need to do is cast these to ints, which can be done with the 
int() method. float() also exists for numbers with decimals. So:

    	tot_local = int(self.local.GetValue())
    	scontolocal_mr = int(self.scontolocal.GetValue())

You could also be using the new properties to access the value, like

    	tot_local = int(self.local.Value)
    	scontolocal_mr = int(self.scontolocal.Value)

which I personally prefer.
