[XSL-FO] right alignment after leader dots (multiple

All, 

In a table cell, I have (potentially) multiple lines of text, left aligned 
For the last line, I want to align a single word ( maximum 4 digits actually) to the right of the cell and fill the space between this word and the rest of the text with leader dots 
I also want this last line to expand outside the box given to the other lines 

The visual effect is that of a second table cell containing the digits (pushed to the bottom) 
and the first cell having leader dots on the last line, reaching out to the right border of the table cell 
(but I figured out that I can not make that happen in FO) 

The following works perfectly using Antenna House 

<fo:table-cell padding-bottom="5mm" keep-together.within-page="always" 
column-number="2"> 
<fo:block keep-together.within-page="always" 
text-align="left" 
end-indent="9mm" 
last-line-end-indent="-9mm" 
text-align-last="justify"> 
<fo:inline>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse sodales tincidunt sapien. Orci varius natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Phasellus quis auctor diam.</fo:inline><fo:inline 
keep-together.within-line="always"><fo:leader 
leader-length.maximum="1mm"/><fo:leader 
leader-pattern="dots" leader-length.optimum="100%" 
/></fo:inline><fo:inline keep-together.within-line="always" 
font-weight="bold"> 2006</fo:inline></fo:block> 
</fo:table-cell> 

The 2006 is nicely right aligned to the cell boundary 

In FOP however the digits are not right aligned 
The text-align-last="justify" is not using the full width of the cell 

Is Antenna House doing a much better job than it should, or is FOP having a bug? 
And are there suggestions or workarounds to make this work in FOP? 

If the question is not clear enough, I can attach screenshots and a full working FO (at least in AH formatter) ... but wanted to start without attachments to begin with 

Thanks for any help anyone can offer
