What you say doesn't contradict what I wrote, we're just talking about different
things (as I see more clearly know, having consulted a dictionary).
The English word "gematriya" refers almost exclusively to the Kabbalistic
activity of counting the numerical values of words, exchanging words with the same
value, finding deeper meanings etc. The Hebrew word "gimatriya" is used to describe
simply the method of counting and writing numbers with Hebrew numerals, but the
English word is usually more specialized.

Well, if that's all we have to go by, it shouldn't be difficult to produce one...
assuming the logical order, something like, let's see...

the hundreds part:
(this assumes you can't have things like 800=T"T, and would rather encode them as TS"K, which
I think is true)
the tens part, with the 15 and 16 coded in as 'fifteen' and 'sixteen'):
the digits part

Combine, rinse, repeat. Will that work, I wonder? (I haven't tested)

To allow for optional gershayim before the last letter, either place lots of (gershayim(?=.$))? in the right
places (introducing also special variants of fifteen and sixteen with gershayim), or remove all 
instances of the symbol from the string before running it through this regexp and then check the correctness of 
gershayim separately with another one.
