Well that's up to your printer supporting CMYK - but no problem.

Well, in Acrobat, it has to color manage your data to the
screen (which is an RGB device) - but when printing, it will either
pass the data through to the printer or can also color manage at that
time, depending on your settings.
Photoshop, however, is a basic RIP - which means it will
render your PDF into the single colorspace of your choice. Gray, RGB
or CMYK - you tell PSD when you open the PDF.

don't do that - it's not what you want...

That definitely says that the TIFF is getting added correctly.
