Script Preparation code:

var isObjectPrototype = (prototype) => prototype && 'modelPrototypeId' in prototype;
var isModelPrototype = (prototype) =>  !isObjectPrototype(prototype);

var data = [...Array(200)].map((_,i) => i % 2 ? ({ id: i, modelPrototypeId: `mp-${i}` }) : ({ id: i }))

Tests:

sort
data = data.sort((a, b) => { return +isModelPrototype(a) - +isModelPrototype(b); });
unshift
data = data.reduce((acc, curr) => { if (isModelPrototype(curr)) { acc.push(curr); } else { acc.unshift(curr); } return acc; }, []);
