I am traveling and cannot test old versions of gnuplot, so I do not
know if tikz mono used to work or not.   I do see that "set mono"
works fine for the tikz terminal, so that is available as an alternative.

I do not think support for the new dashed line mechanism was ever
added to the metapost terminal.

Version 5 uses a different API for dashed lines.
Terminals that do not support the new API are supposed to fall back
to the old dashed line sequence via the generic routine null_dashtype().
I do not know why that is failing for the metapost terminal.
I guess the first thing to check there is whether the fallback mechanism
is failing for all the old un-converted terminals or whether it is specific to 
mp.
