First, get access to the file in Mutagen:

audio = MP3("filename.mp3")

Then, get a reference to the tag you're looking for:

picturetag = audio.tags['APIC:Folder.jpg']

Then, modify the type attribute:

picturetag.type = 3

Then, assign it back into the audio file, just to be sure

audio.tags['APIC:Folder.jpg'] = picturetag

Finally, save it!

audio.save()

Yeah unfortunately Windows doesn't support that version.
Instead of just saving it in ID3v1 try saving it in ID3v3
and ID3v1. I use this in my programs and it works great in Windows 8 and OSX.

from mutagen.mp3 import MP3
from mutagen.id3 import ID3, APIC, error, TRCK, TIT2, TPE1, TALB, TDRC, TCON

audio = MP3([PATH_TO_FILE], ID3=ID3)
audio.tags.delete([PATH_TO_FILE], delete_v1=True, delete_v2=True)
audio.tags.add(
    APIC(
        encoding=3,
        mime='image/jpeg',
        type=3,
        desc=u'Cover',
        data=open([PATH_TO_COVER_IMAGE], 'rb').read()
    )
)
audio.save([PATH_TO_FILE], v2_version=3, v1=2)
