When I import photos from PC to iPhoto can I sort by file name?

I have organised my photos on my PC into folders. For some of these photos I have renamed the files to ensure they always display in a certain order when sorted alphabetically.

I am aware that iPhoto does not really use file names. I see the advantages of this but as I am used to the Windows convention I have the following question:

When I import my photos to iPhoto, will they still be sorted alphabetically by the file names I have carefully created on my Windows PC, or will I need to resort them manually?

Thanks!
