It may depend on what version of Sigil you used. 0.4.0 had an issue. The current 0.6.0 versio (and I think 0.5.x) has a specific fix for the Nook for the cover metadata. Nook's apparently required (or required) you to have the metadata attribute name before the content attribute unlike other devices. When you first tag a cover with Add Semantic the attributes are put into the content.opf file in alphabetical order. However, when you save your EPUB Sigil will switch the order of the metadata to read <meta name="cover" content="cover.png" /> to accomodate the Nook's behaviour. You must save to see this, otherwise it will be listed in standard alphabetical order.
