Applying Cumulative MP5 to HR 9.0 demo database (redundant tax updates issue)

Our production HR 9.0 database is presently up to maintenance pack 5, running on Tools 8.49.  We are in the process of setting up a new HR 9.0 demo database on a server that has Tools 8.51 installed, and need to get this demo database up to the same MP level as our current production database.  From what I could determine from documentation and querying the PS_MAINTENANCE_LOG table on the nw demo database, the initial install did not include any 9.0 maintenance packs, so I must assume that it will be necessary to apply the cumulative MP5.  

With that said, I also noticed that the base demo DB install included tax updates up to and including 10-C. Given that the cumulative MP5 install that I downloaded includes tax updates as far back as 06-F, I'm uncertain how I should proceed with applying this maintenance pack. Is it just a matter of skipping any MP update steps that relate to applying tax updates prior to 10-D?
