Reference of numbered list via display name

I have a numbered list where code property is an index like 1,2,3,…… which i cannot use to pull the properties from the list.

In this list i have 3 other columns p1, p2, p3 and in another module i have a line item which has similar values like p3.

In this same module i am trying to get the values from p2 & p1 in another line items(mP1, mP2) something like - mP2=numberedList.p2[lookup : 'mP3'] where mP3 is line item in module with similar values like p3 in list.

for FindItem i will need to use the value for CODE in arguements which is not going to help in my scenario.

I have also created a module for this particular list dimensioned by the list.
