Reading edition
'Scantling' is used in various senses. Either that of 'rough draft' or, as in Taylor, 'small piece' would do; but it is at least possible that it is not a noun at all, but a direct participle from the verb to 'scantle', found in Drayton, and meaning 'to be deficient', 'come short'. Some, however, prefer the sense 'dimension' or 'measurement', which would make it a sort of varied repetition of 'commensurate'.
