I think it's a transpond issue. One side favours including 'and' (one hundred and one etc.), the other side favors the version without 'and'.
Here, Bingley: let's say I write you a check for one hundred and one dollars; you wouldn't get the money. (Assuming, of course, that the bank employee who processes it is not asleep on the job.)

Edit: deleted something ugly; no need to contaminate the board with my personal anger.
