Hello ruote list,
let me try an experiment.
I've noticed that some questions are fired on IRC (freenode #ruote)
and they get answered (Thanks Torsten, Kenneth et al), but sometimes I
wish I were there to answer, and more importantly, the question /
answer should be more easily reachable / searchable / debatable.
So let me start this "in reply to #ruote" kind of email.

Hello Anthoine,
You could do
---8<---
processes = engine.processes.select do |ps|
ps.variables['customerId'] == 99938
# only variables at the top of the process "/customerId"
#ps.all_variables['customerId'] == 99938
# all variables at any scope level
end

Usually though, you're more interested in workitems.
If you use the StorageParticipant :
---8<---
participant = Ruote::StorageParticipant.new(engine)
# getting a grip on the "storage participant"
workitems = participant.by_field('customerId', 99938)
workitems = participant.by_field('customerId')
# all the workitems that have a customerId field
