I just noticed in File Viewer (random all-files reader) on OS X, that all files have a Misc. attribute called "File Number". It contains values like 17022656, 17022354 and 435457.

I tried to look online for it's meaning, but as it's such a global meaning I couldn't find much of worth.

Does anyone know what this means? Some sort of index in which order files were originally created on the HFS+ partition?

Just curious :)

Im unsure, but this is probaby the inode number for the file. It's the unique identifier for a metadata structure for the file on a volume.
