A WorldCat entry from Bibliothèque nationale de France lists this as having an opus number 11 and being for voice and orchestra. Grove Music lists op.11 as 3 mélodies for voice and piano, so it is likely that this was orchestrated at some point. Since there is no evidence of an arranger at either BNF or Grove, it seems that Vierne himself did the orchestration. It has therefore been tagged for both versions.
