What is the correct syntax for list items that need to contain a quotation mark, etc?

[buran]

import Rhino
import rhinoscriptsyntax as rs
import scriptcontext as sc
 
 
def setDetailScale():
    """
    this script changes the scale of a detail to a selected scale from a listbox
    version 1.0
    www.studiogijs.nl
    """
     
    detail = rs.GetObject("select detail", filter = 32768)
    if not detail:
        return
    detail = rs.coercerhinoobject(detail)
    if not detail.DetailGeometry.IsParallelProjection:
        return
    
    #modify the scale
    scales = {'1/16"=1\'-0"':120, '1/8"=1\'-0"':96, '1/4"=1\'-0"':48,
              '3/8"=1\'-0"':36, '1/2"=1\'-0"':24, '3/4"=1\'-0"':12,
              '1-1/2"=1\'-0"':8, '1/6"=1\'-0"':6, '1:1=1\'-0"':1}

    scale = rs.ListBox(scales.keys(), "Select scale", "Scale detail")
    if not scale:
        return

    intScale = scales.get[scale]
    
    detail.DetailGeometry.SetScale(intScale, sc.doc.ModelUnitSystem, 1, sc.doc.PageUnitSystem)
    
    #lock detail
    items = ["YES","NO"]
    lock = rs.ListBox(items,"Lock Detail/s","YES","NO")
    detail.DetailGeometry.IsProjectionLocked = lock == 'YES'
    
    # if lock == "YES":
    #     detail.DetailGeometry.IsProjectionLocked = True
    # elif lock == "NO":
    #     detail.DetailGeometry.IsProjectionLocked = False

    
    detail.CommitChanges()
    sc.doc.Views.Redraw()
 
if __name__ == '__main__':
    setDetailScale()

If not using python3.7+ scales should be collections.OrderedDict
