Well, actually, it should work both ways, i.e. with the

d.vect census_wake2000 display=shape,attr 
type=point,line,boundary,area,face,centroid attrcol=cat

d.vect census_wake2000 display=shape,cat 
type=point,line,boundary,area,face,centroid

should give the same result (assuming that all features that have a 
category value have a corresponding entry in the cat column of the 
attribute table).

Note that in grass7.0 the use of centroids is not necessary anymore.
