does the order matter when we put gene ids in connectivity map(cmap)?

Hi, I'm currently new to bioinformatics and kind of lost here... I'm currently trying to use connectivity map(cmap) through

broad institue

I submitted up regulated and down regulated gene ids (converting my genes to affy hg-u133a I was wondering - if the order of the up regulated genes(or down regulated genes) does not matter.

Also, while converting the genes (using biomaRt) to affy hg-u133a (in my case from affy hg-u133 plus 2 -> hg-u133a) it creates multiple ids for just one id, like below

209396_s_at ------> 209396_s_at

209396_s_at ------> 209395_at

Is it necessary to include both results(209396_s_at, 209395_at) in my list?
