change dynamic target to use all files for better testing
change order of media query types

media queries that contain "print" and something else, like a "min-width", e.g.: @media print, only screen and (min-width: 60em) should not be put at the end of a file
add a test file for different media queries that contain "print"
add a sort function that considers "print" when sorting media queries
add another test case
