Thanks! You can center the title by adding format field. It is used to well... format the property before it is displayed in infobox. Very useful for adding bold, links or centering text.

<title source="titre">
	<default><center>{{PAGENAME}}</center></default>
	<format><center>{{{titre|}}}</center></format>
</title>

I've added the tag here: http://fr.assassinscreed.wikia.com/wiki/Mod%C3%A8le:Infobox_Mission/Version_de_travail

Or you can also add the following line to css:

.portable-infobox .pi-title {
	text-align:center;
}
