initialization dependencies

I'm playing around with Moose in a real world work scenario and came  
across an interesting question...

I'm working on a series of reports that mostly similar, you have to

build up limits to a general query.
pull that query
organize the data
pull all the data together for display and some math

so you need to get things like:

limits
value X
value Y

value X and Y depend on limits to be pulled...

limits is like this:

has 'limits'  => ( is => 'rw', isa => 'Str', builder =>  
'build_limits' );

could X and Y also be done with builders when they depend on limits  
being set?
is there a way to order the initialization of attributes? do i have to  
order it? is
moose smart enough to order them correctly ( pie in the sky there )?
