I can only answer this last one. In AlphaX, I have installed coercion handlers between 'alis' and ‘utxt’ types, which is why your instruction succeeded.

static pascal OSErr Alpha_UtxtToAlisCoerceProc(const AEDesc *fromDesc, DescType toType, long handlerRefCon, AEDesc *toDesc);
static pascal OSErr Alpha_AlisToUtxtCoerceProc(const AEDesc *fromDesc, DescType toType, long handlerRefCon, AEDesc *toDesc);
