You don't even need to test for empty; you can use 'put ... after
tArray[key]' whether it is currently empty or not.
so you could simply do
set the itemDel to tab
repeat for each line tRecord in tManyRecords
put item 1 of tRecord into tParent
put item 2 of tRecord into tChild
put tChild & comma after aArray[tParent]
end repeat
put aArray[138] into msg -- 43,131,6, should appear in the msg box
NB - you do get the trailing comma, so you need to handle that properly
in any subsequent processing
e.g. repeat for each item T in aArray[138] ... is fine.

This might get you started with your first problem of how to avoid
overwriting data.
Assuming your second long list is tab separated and been read into a
variable tManyRecords
set the itemDel to tab
repeat for each line tRecord in tManyRecords
put item 1 of tRecord into tParent
put item 2 of tRecord into tChild
if (aArray[tParent] = empty) then
put tChild into aArray[tParent]
else
--add another child
put aArray[tParent] & comma & tChild into aArray[tParent]
end if
end repeat
put aArray[138] into msg -- 43,131,6 should appear in the msg box

--comma is a BAD choice unless you KNOW it's ALWAYS going to be a number

a thousand separator
It's really just a matter of testing whether the Array Key is empty or not.
