Up-Values with GroebnerBasis

The Solve function in Mathematica version 3.0.1 uses GroebnerBasis but
GroebnerBasis does not use up-values with which I define my own kind of
numbers. So, how can I use Solve to quickly find solutions to equations
with coefficients which have up-values for addition, subtraction,
multiplication, division, and powers defined by my own rules for B
numbers(a list of numbers wrapped by the head B[{a,b,...}]) in version
3.0.1? It works fine in version 2.1, 2.2 and 2.2.2.
