Hmm... nice little challenge. How about:
put 1 into tIndex
repeat for each line tLine in tList
add 1 into tCounter[tLine]
switch tCounter[tLine]
case 1
put tLine into tOrder[tIndex]
put tIndex into tLocator[tLine]
break
case 2
-- go back and sequence the first instance
put tLine&"-"&1 into tOrder[tLocator[tLine]]
break
default
-- sequencing now
put tLine&"-"& tCounter[tLine] into tOrder[tIndex]
break
end switch
add 1 to tIndex
end repeat
repeat for each key tIndex in tOrder
put tOrder[tIndex]&cr after tResult
end repeat
