Build order not correct

Although quite a few JIRA issues here give the impression that the build order with continuum should be the same as in the M2 reactor, this is absolutely not true for us here.
All of the modules are built in something like alphabethical order, but not quite - it's just strange and not very helpful.
Our project is quite big (67 modules) and we use almost only version ranges, e.g. [1.0,2.0) - maybe it's that? The dependencies of the projects are being shown in the project view, example:

Group Id  	Artifact Id  	Version
de.xpm.ejb 	common 		[1.0,2.0)
commons-el 	commons-el 	[1.0,)
javax.servlet 	jsp-api 		[1.0,)
de.xpm 		xpm-portal-libs 	[1.0,2.0)
de.xpm 		mock 			[1.0,2.0)
de.xpm 		xpm-global-common 	[1.0,2.0)
de.xpm 		xpm-portal-common 	[1.5,2.0)
de.xpm.ejb 	rolesystem 		[1.0,2.0)
de.xpm 		components 	[1.0,2.0)
com.sun.faces 	jsf-impl 	1.1
javax.servlet 	jstl 		1.1.2
de.xpm.ejb 	shop 		[1.0,2.0)
de.xpm.portlet 	Meta 		[1.0,2.0)
jsfunit 	jsfunit 	0.1.0
