It's not so complicated:
if !exists("g:matchparen_timeout")
let g:matchparen_timeout = 300
endif
if !exists("g:matchparen_insert_timeout")
let g:matchparen_insert_timeout = 60
endif
...
if mode() == 'i' || mode() == 'R'
let timeout = exists("b:matchparen_insert_timeout") ?
b:matchparen_insert_timeout : g:matchparen_insert_timeout
else
let timeout = exists("b:matchparen_timeout") ? b:matchparen_timeout :
g:matchparen_timeout
endif

ZOOT: I'm afraid our life must seem very dull and quiet compared to yours.
We are but eightscore young blondes, all between sixteen and
nineteen-and-a-half, cut off in this castle, with no one to protect us.
Oooh. It is a lonely life ... bathing ... dressing ... undressing ...
making exciting underwear....
