It's not really a bug in numeric, but rather a quirk you'll have to get used to:

In [6]: logical_and(a>2.,a<4.)
Out[6]: array([0, 1, 1, 0, 0])

The problem is that and/or can't be overloaded.  So Numeric provides a familiy
of logical_* functions for this purpose:

logical_and  logical_not  logical_or   logical_xor
