To Reproduce

private _pp = [[0,0,3,"Head"],[0,0,4,"Body"],[0,0,1.00125,"LeftArm"],[0,0,1.56359,"RightArm"],[0,0,1.1933,"LeftLeg"],[6.17301,2.05767,1.80874,"RightLeg"],[0,0,1,"#structural"]];
_pp sort false;
_pp

[[0,0,1,"#structural"],[6.17301,2.05767,1.80874,"RightLeg"],[0,0,1.1933,"LeftLeg"],[0,0,1.56359,"RightArm"],[0,0,1.00125,"LeftArm"],[0,0,4,"Body"],[0,0,3,"Head"]]

Expected behavior
[[6.17301,2.05767,1.80874,"RightLeg"],[0,0,4,"Body"],[0,0,3,"Head"],[0,0,1.56359,"RightArm"],[0,0,1.1933,"LeftLeg"],[0,0,1.00125,"LeftArm"],[0,0,1,"#structural"]]
