// Underscore was loaded last, so this saves an instance of underscore and resets _ to it's previous value (lodash).
var _underscore = _.noConflict();
// This saves an instance of lodash and resets _ to it's previous value (undefined).
var _lodash = _.noConflict();

Tests:

Native
users.find(function (o) { return o.age < 40; })
Underscore
_underscore.find(users, function (o) { return o.age < 40; })
Lodash
_lodash.find(users, function (o) { return o.age < 40; })
