Sharepoint Designer - Creating a simple Workflow, check status of another Workflow

Question

I'm trying to create a simple workflow using the Sharepoint Designer. We already have one user-defined workflow, called Internal Approval. This creates a column with the same name.
Basically, my workflow should perform:
Conditions:

if Internal Approval equals Approved 
   and Status equals Draft //custom field I want to set, this works

The problem, after a quick debug, is that the Internal Approval does not equal to Approved nor contains it, Internal Approval equals 16.
The question: what is this number, and can I rely on it always being 16 for an approved workflow?
Or better, how can I check a if another workflow was approved?
