Script to delete alternate layout

I am writing a script that puts ID documents into the correct folder and naming structure to be batch imported into a folio. The documents have two alternate layouts, the original "Print" layout and an "I" layout for ipad. I want the script to delete the "Print" layout pages before processing the document. This is effectively the first section of the document. If I try to target it as below, I receive an error that says cannot delete the doc's default section.

var allSections = myDoc.sections;   var numSections = allSections.length;      if (numSections > 1){       allSections[0].remove();       }

How do I correctly target this section, and what is the correct syntax for targeting it by it's altenate layout name, "Print"

Many thanks,

Tim
