D'oh!  The third line was supposed to read,

    for seq, content in sorted(t_order + m_order):

Sorry...

Actually, you could use sorted()'s key argument to simplify that.

    for content in sorted(text + media, key=lambda item: item.seq):
        display_text_or_media(content)

Is that not Pythonic enough for you? (-:  Perhaps this is.

    from itertools import chain
    for content in sorted(chain(text, media), key=lambda i: i.seq):
        display_text_or_media(content)
