This one will (like Kai's) uses the TIDs to find the item. It also
returns ALL of the occurrences of the search term.

Snip

This (faster) alternative is an all-occurrence variation on my original
suggestion:

==============================

property d : ASCII character 1

to getPosition of i from l
if i is not in l then return 0
set {n, o, t, text item delimiters} to {0, {}, text item delimiters, d & d}
set {l, text item delimiters} to {d & l & d, d & i & d}
set {l, text item delimiters} to {l's text items 1 thru -2, d & d}
repeat with i in l
set i to i as string
if i is not "" then set n to n + 1
tell n + (count i's text items) to set {n, o's end} to {it, it}
end repeat
set text item delimiters to t
o
end getPosition

set txtList to {"nine", "six", "six", "two", "sixteen", "sixty", "six"}
getPosition of "six" from txtList
--> {2, 3, 7}

==============================

Nice Kai, and with Richard Morton's modifications it's 77 percent faster OMM.
