  But when count is equal to 4, the variable part of the result should be the 
  same the as the hard-coded "4" part of the result.  Could someone please 
  tell me why it doesn't work?

you haven't shown the relevant bit of your code (the definition of the
variable). But we can make some guesses

If the variable  count  oes have the value 4
as in
<xsl:variable name="count" select="4"/>
then as you say, [4] and [$count] will work in the same way.

If however it has a value that is (or will be cast to) "4"
as in
 <xsl:variable name="count" select="'4'"/>
<xsl:variable name="count">4</xsl:variable>
then [$count] will work like ['4'] which being a non-numeric filter will
work like [boolean('4')] which will work like [true()] as boolean()
returns true on a non-empty string (or non empty node set)
and a predicate  of true() will not filter your node set at all.
