Re: “is 6 dollars less than 5 pounds”, this is how Wolfram Alpha interpreted it: “TrueQ[$6 (US dollars)<5 lb (pounds)] ”. It interpreted pounds as a unit of mass, not as the currency and gave “False” as a result. You have to pick “British Pounds” from a list of other interpretations in order to get the right answer, “True”. I don't know what it says about your argument, other than it's hard to tune the engine.
