Undo page number alignment and remove dots from list of algorithms

Question

I am using the classicthesis theme and I am trying to make my list of algorithms the same format as my lists of tables and figures. I am using the algorithm2e package. Here is how it looks at the moment.

I have tried the answers to this question but they do not work, presumably because they use the algorithm package instead. Using the accepted answer, the list of algorithms takes the name of the list of figures, but doesn't list anything:

The other answer just doesn't change anything at all.

Since the classicthesis template is massive, I am not sure how to provide a minimal working example... The following code reproduces the issue, with the original classicthesis.sty file from the classicthesis template.

\documentclass{scrreprt}

\usepackage{classicthesis}
\usepackage{algorithm2e}

\begin{document}

\listoftables
\listofalgorithms

\newpage

Here is Algorithm \ref{alg:some_alg}.

\begin{algorithm}
    \For{something}{
        something else
    }
    \caption{Some algorithm.}\label{alg:some_alg}
\end{algorithm}

Here is Table \ref{tab:some_table}.

\begin{table}
    \centering
    \begin{tabular}{cc}
    some line & some content \\
    some other line & some other content \\
    \end{tabular}
    \caption{Some table.}
    \label{tab:some_table}
\end{table}

\end{document}

I wish to remove the dots from the algorithms table, as well as to undo the alignment of the page numbers so that it looks like the list of tables above.

The key is the tocloft command \newlistof. The actual formatting is performed by \l@algocf.

\documentclass{scrreprt}

\usepackage{classicthesis}
\usepackage{algorithm2e}

\makeatletter
\newlistof{algorithms}{loa}{\listalgorithmcfname}%
    \renewcommand{\cftalgorithmsleader}{\hspace{1.5em}}%
    \renewcommand{\cftalgorithmsafterpnum}{\cftparfillskip}%
    \renewcommand{\cftalgorithmspresnum}{\algorithmcfname~}%
    \newlength{\algorithmslabelwidth}%
    \settowidth{\algorithmslabelwidth}{\cftalgorithmspresnum~999}%
    \addtolength{\algorithmslabelwidth}{2.5em}%
    \cftsetindents{algorithms}{0em}{\algorithmslabelwidth}%
    \let\l@algocf\l@algorithms
\makeatother

\begin{document}

\listoftables
\listofalgorithms

\newpage

Here is Algorithm \ref{alg:some_alg}.

\begin{algorithm}
    \For{something}{
        something else
    }
    \caption{Some algorithm.}\label{alg:some_alg}
\end{algorithm}

Here is Table \ref{tab:some_table}.

\begin{table}
    \centering
    \begin{tabular}{cc}
    some line & some content \\
    some other line & some other content \\
    \end{tabular}
    \caption{Some table.}
    \label{tab:some_table}
\end{table}

\end{document}
