How to set the order of side blocks

[zeropoint]

I was wondering how to set the order of side blocks when you have both xml blocks and widget blocks? Seems the cms xml side blocks order get set according to each other and the widget blocks according to the widget blocks. Like they don't recognize each other. 

Like you can have widget blocks in a certain order but if you add a xml cms side block it will go below other xml side blocks but not under the widget blocks and vice-versa.  For example, I'm trying to get a custom xml block to be the very bottom block with this code:

        <reference name="right">
            <action method="unsetData"><key>cache_lifetime</key></action>
            <action method="unsetData"><key>cache_tags</key></action>
            <block type="core/template" name="quotes" as="quotes" after="bestseller.single" template="mycmsblocks/quotes.phtml" />
        </reference>

but it goes below the last xml block ignoring any widget blocks. 

or how would one set the cache_lifetime for a widget block?

Thanks!
