[Space Age] Inserters - Spoiled Priority

[hgschmie]

In Space Age, all inserters have a checkbox called "Spoiled Priority" and a radio selection between "Spoiled first" and "Fresh first". I was trying to understand what attribute on LuaEntity reflects those settings but it is unclear to me. Anyone can help me out?

Thanks in advance.
