What did James V mean by “afferandly”?

The OED gives it as ‘appropriately, suitably’. Ultimately from afeir, and then from ‘Anglo-Norman and Middle French aferir, afferir, to appertain, to be appropriate, to be fitting.'

The Dictionary of the Older Scottish Tongue (DOST) defines afferandly/ afferandlie:

DSL - DOST Afferandly, adv. [f. prec. Cf. Efferandly.] Appropriately, suitably. — Bodin in hors and geir … afferandly to yowr honor and owris; 1536 Wemyss Corr. 4. To find sufficient cautioun … afferandlie as is afoirwrittin; 1576 Edinb. Test. IV. 221.

Note that the entry cites the same passage as in the question.
