Try doing arithmetic with roman numerals!  My impression is that the
Arabic notation was adopted (with much discussion about its sanity,
morality, etc) after merchants conceded that Roman numerals were too
clumsy for business computations.  Considering how the Romans blew the
notation, I wouldn't give them much credit for picking the right digit
order.  Given the entrenched big-endian order in most of the spoken
languages, the merchants may have hesitated to adjust the notation for
fear that it would be hard to speak the numbers (though German numbers
up to 100 are little-endian!).  More likely, they just adopted the
notation verbatum without thinking much about it.
