Close, but it needs spaces around the equal signs, like:

exten => _X.,1,GotoIf($[${EXTEN:2:1} = 1]?20)
exten => _X.,2,GotoIf($[${EXTEN:2:1} = 2]?30)

Or if you want it to not crash if EXTEN is empty:

exten => _X.,1,GotoIf($["${EXTEN:2:1}" = "1"]?20)
exten => _X.,2,GotoIf($["${EXTEN:2:1}" = "2"]?30)
