Back not sure why people need a pattern for all things ;-)
anyway, to answer your question, there are some business rules engine that lets you define the rules out of your code and at run time your program will make a call to that rules engine component passing the desired values to process the rule and voila you get the result back. simple thing but people surely wish to call it business rule engine which is to me is just another hype.
in your case, if you have such rule for every customer, most probably you would like to fix the MAX_BREAD for every customer. before placing an order check that condition. that's it. now what you call defining business workflow model for order processing ;-)
