Sorting Like In Dictionary, Help Plaseeee?

I need to sort my data more than just order it using Order by clause.
I need the, to appear so that they are sorted like in dictionary's order.
example: if I have 0.1 and 0.2 and 0.11
They need to be ordered into 0.1 then 0.11. then 2.0. etc.

I thought I could use Val() function but it wasn't a successful attempt. Anyone can help me please?

I'm using ColdFusion and this is one of the query :

<cfparam name="sort" default="goal_cd">

<cfquery name="GetTheme" datasource="#application.OUSDSN#">

Select goal.*,theme.*
From goal,Theme
Where goal_theme_id = theme_id
Order by #sort#

<cfif sort is "goal_cd">
Order by Val(#sort#) <--------------------- This doesn't work!!!
<cfelse>
Order by #sort#

</cfif>
</cfquery>
