Chris,

I got it to work. Here's what I did.

I downloaded the wsdl file to a local file and looked at the method  
call in detail. I noticed something interesting and out of place.  
Look at this definition and take a close look at capitalization:

    <wsdl:message name="getBPListRequest">

       <wsdl:part name="shortname" type="xsd:string"/>

       <wsdl:part name="authcode" type="xsd:string"/>

       <wsdl:part name="projectNumber" type="xsd:string"/>

       <wsdl:part name="BPName" type="xsd:string"/>

       <wsdl:part name="fieldnames" type="impl:ArrayOf_xsd_string"/>

       <wsdl:part name="filterCondition" type="xsd:string"/>

       <wsdl:part name="filterValues" type="impl:ArrayOf_xsd_string"/>

    </wsdl:message>

Please notice that the fourth element, the one that is consistently  
screwed up, has a name starting with a cap letter. So what I did was  
create an edited version of the wsdl and changed that name from  
"BPName" to "bpName" in both places it shows up (for that specific  
method definition). I then ran your code again and it produced the  
correct soap request as shown below:

<env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema"
     xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <env:Body>
     <n1:getBPList xmlns:n1="http:// 
general.service.webservices.messenger.skire.com"
         env:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
       <shortname xsi:type="xsd:string">one</shortname>
       <authcode xsi:type="xsd:string">two</authcode>
       <projectNumber xsi:type="xsd:string">three</projectNumber>
       <bpName xsi:type="xsd:string">four</bpName>
       <fieldnames n2:arrayType="xsd:string[1]"
           xmlns:n2="http://schemas.xmlsoap.org/soap/encoding/"
           xsi:type="n2:Array">
         <item>five</item>
       </fieldnames>
       <filterCondition xsi:type="xsd:string">six</filterCondition>
       <filterValues xmlns:n3="http://schemas.xmlsoap.org/soap/ 
encoding/"
           xsi:type="n3:Array"
           n3:arrayType="xsd:string[1]">
         <item>seven</item>
       </filterValues>
     </n1:getBPList>
   </env:Body>
</env:Envelope>

I don't know if the SOAP standard allows for those names to start  
with capitals, but for sure the ruby code doesn't handle it correctly.

I imagine the right way to fix this is to check the SOAP standard to  
see what it says (or if it's mute on the topic of capitalization) and  
then, depending on that answer, modify the SOAP library to downcase  
these strings or just the first letter.

Anyway, mystery solved!
