strong/weak typing and pointers

which brings me to another related question.

I understand strong/weak typing is more like a continuum --
is there kind of a programming langauges hierarchy sorting various
langauges accoring to "type-strongness" that is generally agreed upon?

I'd be interested in a hierarchy containing some of the following
languages: ANSI-C++, C, Perl, Python, Pascal, ML.
(because these happen to be some of the languages i know a bit ;-) )

Would the following be justifiable?

    Perl < C < C++ < Pascal < Python < ML ?

Or does anyone have a pointer?

Best regards,
gab.
