Another LC9.6.9rc2 regression? This time with Datagrids

Hi Mike,

I suspect some change was made in the Datagrid scripts, such as a move 
of some code from a stack to a script-only stack or some engine change 
in how comparisons are done, variables interpreted, etc. that 
inadvertently impacted the Datagrid code, but while we use a lot of 
Datagrids, I have never really tried to follow or understand the 
internal scripts and I'd can't invest the time just now (too much else 
taking priority). I have I think, clearly demonstrated this is a 
regression - code works under LC 9.6.8 and fails under LC 9.6.9rc2, so 
it's now up to Livecode, Ltd. (or yourself IF you want to dive right in 
;-) to solve the bug.

Our choice boils down to [A] Build under 9.6.8 and not have a fix for 
the Non-Gregorian calendar crash under macOS which was fixed in 969rc2 
OR [B] wait until LC staff or someone fixes this and we find no other 
regression in 9.6.9. I think we've now found 3 regressions in 3 weeks, 
which is not a good sign for 9.6.9.

BTW, thank you again for your help with the Ask and Answer regressions!
