Migration Scripts that use Static Data

What is the solution to writing a migration script that uses static data to process an update?
Example:
I have a Properties table that has a foreign key to PropertyTypes. Business requests that a new property type be added to the system, and that any existing properties currently marked as "Other" reference the new property type instead.
Development:
Create new property type, which is in static data. Write a migration script to update existing property records to use the new PropertyTypeId where the current PropertyTypeId is equal to "Other."
Issue:
Running DLM Automation to apply the changes using Continuous Deployment will fail because the migration script runs before the static data.
This is a very basic situation when it comes to scripting out changes. How can this be done using DLM? We don't want to abandon Red Gate Source Control to move to a migration type methodology of Ready Roll. Although, at this point it seems the DLM Automation tools won't work for us.
