Output 2 Extra Records That Are Sorted

Question

I want to map a repeating group to a similar output repeating group and also add 2 extra records to the output with the output sorted on the first element.
Here's my input...
<Request>
<Records>
<OrderType>4</OrderType>
<OrderValue>01</OrderValue>
</Records>
<Records>
<OrderType>4</OrderType>
<OrderValue>01</OrderValue>
</Records>
<Records>
<OrderType>4</OrderType>
<OrderValue>02</OrderValue>
</Records>
<Records>
<OrderType>4</OrderType>
<OrderValue>03</OrderValue>
</Records>
</Request>
Here is my desired output...
<Request>
<Records>
<OrderType>1</OrderType>
<OrderValue>05</OrderValue>
</Records>
<Records>
<OrderType>2</OrderType>
<OrderValue>00</OrderValue>
</Records>
<Records>
<OrderType>4</OrderType>
<OrderValue>01</OrderValue>
</Records>
<Records>
<OrderType>4</OrderType>
<OrderValue>01</OrderValue>
</Records>
<Records>
<OrderType>4</OrderType>
<OrderValue>02</OrderValue>
</Records>
<Records>
<OrderType>4</OrderType>
<OrderValue>03</OrderValue>
</Records>
</Request>
I know I need to use Inline XSLT but cannot work out how to output the 2 extra records and ensure Order Type is in sequence.
Both input and output use the same schema.

Hi Stewart,
If you use the following XSLT this add two extra nodes and sort the existing (input) nodes by OrderType. For sorting the existing node by OrderType, I am using
Muenchian here. This XSLT outputs as you have wanted. I have given comments for your understanding.
<?xml version="1.0" encoding="UTF-16"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:var="http://schemas.microsoft.com/BizTalk/2003/var" exclude-result-prefixes="msxsl var" version="1.0">
<xsl:output omit-xml-declaration="yes" method="xml" version="1.0" />
<xsl:key name="groups" match="Records" use="OrderType"/>
<xsl:template match="/">
<xsl:apply-templates select="/Request" />
</xsl:template>
<xsl:template match="/Request">
<Request>
<!--Add two extract node-->
<Records>
<OrderType>1</OrderType>
<OrderValue>05</OrderValue>
</Records>
<Records>
<OrderType>2</OrderType>
<OrderValue>00</OrderValue>
</Records>
<!--Sort the existing node by Order Type-->
<xsl:for-each select="Records[generate-id(.)=generate-id(key('groups',OrderType))]">
<xsl:sort select="OrderType" order="ascending"/>
<xsl:for-each select="key('groups',OrderType)">
<Records>
<OrderType>
<xsl:value-of select="OrderType/text()" />
</OrderType>
<OrderValue>
<xsl:value-of select="OrderValue/text()" />
</OrderValue>
</Records>
</xsl:for-each>
</xsl:for-each>
</Request>
</xsl:template>
</xsl:stylesheet>
Note: You may need to change the namespace as per your schema definition.
