After a bit of tweaking, I'd suggest:

sudo find /opt/local -regex '.*/[^/]\{1,\}\.mp_[[:digit:]]\{9,10\}' -print -delete

If you don't have any very old files, or files which were created when the clock was reset:

sudo find /opt/local -regex '.*/[^/]\{1,\}\.mp_[[:digit:]]\{10\}' -print -delete

Or, if you want to ignore anything in a ‘var’ directory:

sudo find /opt/local  \( -not -path '*/var/*' \) -regex '.*/[^/]\{1,\}\.mp_[[:digit:]]\{9,10\}' -print -delete

The first one should be quite safe; user files are unlikely to end with ‘.mp_’ followed by 9–10 digits ;-)
