Ah, you apparently can't mix keyword parameters with even one
non-keyword parameter.  Try this:

on insertion of anItem into aList at aPosition
    return (items 1 through (aPosition-1) of aList) & anItem & (items
aPosition through end of aList)
end insert

set myList to {itemA, {itemM, x}, {itemP, y}}
set myList to insertion of itemZ into myList at 2
myList
 -- {itemA, itemZ, {itemM, x}, {itemP, y}}
