Bundle label (table) value as a list expression?

This is for a dynamic routing / job shop model. Routing data is stored to the flowitem on a bundle label, Routing. Another label, stepRow, indicates which routing is next. The stepRow label is 1 on flowitem creation to begin with the first routing, and as each routing process is complete the stepRow label is incremented. The Routing label looks like this:

Process	Process Time
200	1.5
400	.5
100	22

To push to a list with the next process as an expression, I have tried the following with some minor variations:

(1) return value.Routing[value.stepRow][1];
(2) return value.labels("Routing")[value.stepRow][1];
(3) 
Object thisItem = value.as(Object);
Table routing = thisItem.Routing.as(Table);
return routing[value.stepRow][1]; //also with .value

These give either type mismatches (value is Variant by default) or "Unknown command labels being called."

Machines in the model will pull from the list where a flowitem's next process matches its own, and will likewise get process times from the Routing label.

I made it work by writing the value of interest on a new label and pushing that onto the list. The new code might work to pull the value directly from the bundle label to the list, but I have not tried it. List expressions do not seem to like blocks of code. The code to retrieve and write to the new label is:

item.newLabel = item.labels["Routing"].as(Table)[item.stepRow][1];

It is then pushed to the list with the expression:

value.newLabel
