Under the assumption that 'A' only appears as length-1 string in Prefix the following diff makes that stylesheet work on XSLT 1.0 processors:
$ diff mark.xsl mark1.xsl 10c10 < <xsl:sort select="if( Prefix!='A' ) then Prefix else ''"/> ---<xsl:sort select="translate(Prefix,'A','')"/>$

My bad ... in my haste I neglected to think of the behaviour triggered in the "if" statement when the Prefix element is absent. When an operand of the comparison operator is the empty set, the comparison returns false.
It worked for me when I turned the expression inside out:
<xsl:sort select="if( Prefix!='A' ) then Prefix else ''"/>
Now the same '' value is used for sorting if the prefix is 'A' (the test calculates as false) or the prefix is absent (the test defaults as false).
I hope the illustration below helps. Note how document order is maintained for all records that have no prefix or the prefix is 'A', thus proving they are being sorted with the same value.
